I don't think there is anything 'unserious' about an armed conflict with a state, and I don't think you can be serious about portraying it that way - its a flippant thing to say.
Again, I don't think its true that they didn't have support from the peasants. Certainly that's been claimed by the anti-communists, but they always say that about their enemies.
I don't think conflicts occur on somebody's whims, there is always a reason. A long (and ongoing) conflict of this kind could not have occured without there being a good reason for it, and also a possibility of victory.
I think Vijay Prashad wrote something about Russia like its viewed in the West as either the Vatican or hell... not hell, he uses a different word, its a much better phrase than I'm able to remember. But the point being that dichotomy between the source of moral authority, or the opposite (I guess alluding to Moscow as the fourth Rome).
On this particular topic, my own view is that Russia is restricting the rights/priviledges of what they term the 'international' LGBTQ movement, because I think the west uses wealthy urbanite associations of that kind in Russia (particularly St Petersberg/Moscow) for spying activities. At the same time, Putin has said (though ofc its necessary to examine what is done, not just what is said) that the LGBTQ community is part of Russian society, and shouldn't be attacked or victimised - this is probably because as a legalist ruler he wants to be in compliance with various legal obligations, and also doesn't want internal conflict. I think he isn't particularly opposed to the restrictions, because of the support it wins from the Orthodox church.
I wonder also with this particular topic, how much of the impetus for these kind of anti-progressive movements is to do with political kompromat. Certainly I don't think most of the elite, like aristos or capitalists for example, really care about sexual preferences, but rather its a useful political tool if the masses (are persuaded to) consider it immoral. Like with the 'Lavender Scare' in the US, but then I've also seen a CIA testimony saying that they (I paraphrase) 'like homosexuals because they're useful' referring I think to the usefulness of having something over someone. I suppose I mean, I wonder how much (alongside other factors) the passage of anti or pro LGBTQ laws is to do with wanting a political weapon, or alternatively as a kind of disarmemant treaty among the ruling classes.
