Using this definition. 'Loves his motherland' certainly applies to you, and there's little difference between 'dumb' and 'willfully ignorant' in the 'seeing but disregarding' sense: You repeately stated that all this is not about what's good for Russia, but about what's good for, speaking bluntly, the Russian national ego. Of course you jump through some intellectual hoops to justify your position or at least to analyze and dissect it, so there may be some subtleties I'm missing.
With all due respect, Helgo, I think that your anti-nationalist (sorry if I am using wrong terminology here) German upbringing has left you a tad biased towards people who hold onto irrational, nationalistic ideas. As I've mentioned in the terrified thread, defending the Motherland has always been a big part of Russian national identity, with sacrifice on one's life in a war to defend one's people being one of the greatest acts of heroism, and so I, and many of my compatriots, are not supporting the Donbass rebels, and, by proxy, Russia, out of blind jingoistic pride like your statement seems to imply, but because the Donbassians have allied themselves with Russia, and in doing so, became someone we ought to protect, even if our sacrifices will be ultimately futile and our cause will not be objectively just. Consider the kinship you told me you felt with secular Syrian rebels and Euromaidan activists - I feel the same kinship with the Novorussian separatists. It's not based on anything rational, but rather is an integral component of my system of values, similarly to how belief in democracy is an integral component of yours. I'd say that I am not being ignorant, even willfully, because I fully acknowledge how questionable, morally and otherwise, my position is to an external observer, and realise that I am not doing the right thing in the sense of Bismark's realpolitik.
To clarify, when I mentioned "Russian national pride" earlier, I didn't mean it a sense of 19th century imperialistic ambition, but rather in a sense of this moral imperative to defend our own.
