So might as well keep beating it.
Giustino presents talking points for arguing with Russian nationalists. By coincidence, I have spent all morning reading more LiveJournal stuff on Estonia and Russia, and I have a couple points to make.
1) As pointed out in the comments, your purpose is not to convince your opponents, because they are not rational and will not be swayed by reason or logic. Your target audience instead are the lurkers, the people who have not formed an opinion or are not locked into any side yet.
The upshot of this is that changing the topic does not accomplish your goal. If you show your opponent less knowledgeable than you are, or incapable of arguing his point in a chosen context, that certainly improves your own reputation within the forum, gives you a higher standing (the social dynamic of flame forums is a very exciting topic that I may touch upon later). It does not, however, convince the lurkers. They are there, and lurking, because they don't have sufficient information on the topic; they are more likely to identify with the loud simpletons who bring forth uncomplicated, if subtly false, points.
What you need to do is to debunk the opponents' arguments, specifically the ones they put to you, methodically, consistently and convincingly. Use your knowledge and your sources to make the loud simpleton appear a complete moron who doesn't know what the fuck he is talking about. If you perfect this technique, you will eventually reach a level of discourse skill where you can make your opponent's words to discredit him. The true zen master will not even need to respond for the audience to start seeing the weak and implausible points in the opponent's argument; the very act of attack on the zen master is what defeats the attacker.
(I will not claim to have reached enlightenment, however on at least one prominent political forum - a heavily moderated one, where the discourse does not deteriorate into feces-slinging - I had been used as a measure of convincingness. I.e. "your argument is so stupid, it convinces me to take the opposite stance more than ten Flasher T-s could.")
2) It is not fair to call our opponents nationalists. Whether they are Nashi comissars, or flamers of conviction, nationalists they are not. For the purpose of this argument, Russia is not a nation, it is a state. The Kremlin-jugend we are fighting in cyberspace is not representing the Russian nation, it is representing the Russian state and its government, which are for most intents and purposes a single entity.
Russian nationalists do exist, and they are something else entirely. Ostensibly they are our allies, because they have come out firmly on Estonia's side during the conflict. However, after having the opportunity to observe them more closely, I do wonder if they're the sort of allies we really want. Being juxtaposed to Russian cronies, Russian nationalists are professional rebels, continuing the fine tradition of Soviet dissidents: they will take any position that is against the Kremlin. They will stand for Estonia, or for Georgia, or for Juschenko, or for neonazis, or for gay rights - not necessarily all at once, for they are far from a cohesive organization, but as a group they have enough in common to focus on a single enemy. Their fight is difficult, long, and quite possibly hopeless.
However, their fight is not our fight, and it would be extremely foolish for us to get dragged into it.
The pro-Estonian contingent does have an endgame, a specific goal that it is trying to achieve: getting Russia to lay off. If Putin announced tomorrow that the Bronze Soldier is Estonia's private matter, that Russian-speakers in other countries are welcome in Russia if they choose to leave but otherwise are on their own, that Russian companies are encouraged to do business with Estonia; that Russia couldn't give a flying fuck about Estonia in general - we will be satisfied and grateful. These are the terms of armistice which we will accept. If Putin, or his heirs, then continue to tighten the screws on their own population and fuck with various former Soviet states, sell nuclear fuel to Iran, send submarines to place flags on the ocean floor; then we shall certainly be concerned, but we shall stand on the sidelines and shrug.
The ultimate fate of Russia is not our problem.
Russian nationalists are also not our problem, because in large part they are somewhat unpalatable characters. Concentrating on the Russian nation as juxtaposed to the Russian state has left them very hardcore; their principal objection is the massive number of immigrants, guest workers and traders from the North Caucausus, as well as the corrupt police force and civil service. Their ideology is based on the understanding that the Russian people are fundamentally competent, cultured and Good*. It is simply the foreigners, and the corrupt government, that are keeping great Russia down. The moderate element here might advocate a retreat into traditional Russian territories stretching to the Volga river**, while the more extreme contingent here push for absolute Russian dominance on all territories comprising the multinational Russian Federation; whether or not any of them have a point, this shit is far too heavy for us, as Estonians and Europeans, to get into. And at the end of the day it's none of our business.
Small nations cannot afford ideals.
* Someone asked if presuming that Russians are by default incompetent and incapable of building a democracy is in fact a fascist assumption. It's a very good point, and I'll admit that the presumption itself is Evil, but I just can't escape the thought that if it looks like a duck, walks like a duck and quacks like a duck...
** My personal opinion is that this might be the solution - Russia giving up territories which are not authentically Russian, territories which the Empire and then the Soviet Union conquered out of greed and were never able to satisfactorily control. A Russia that stretches from Novgorod to the Volga would be far more manageable and could eliminate the irritating factors that bring out the asshole in a Russian; and the worst case scenario then is that the Russians will only be hurting themselves. This leaves out Siberia of course, but the Russian bits of it - the ones that were previously populated by bears - are nationalist in their own way. The people who actually manage the natural resources that make Russia rich have a different attitude from the Moscow beltway wanks, and as they would gladly make Siberia an independent state given the chance, they would probably do well, and even build the model Russian community - sort of the Switzerland to Great Russia's Germany. Then all they have to do is fight off China.
Of course, none of this is actually in any way realistic.
