Mister Terrorizer, I would be silent about pathalogical patriotism if I would be you. Better look at the mirror and around you, such level of "kvasnyj patriotizm" like in your country is almost impossible to reach.
Luckily, you're not me and I'm not you

By the way, "квасной" and not "квасный". It's nothing wrong to be patriotic, in fact, it's completely normal to love your country and to be proud of it where there are some sound reasons to do so. But ZizzitSlo wrote about really different thing which is patriotism only by its name. It's a 'faux patriotism' which always needs some enemy in order to feel 'national pride', which always underlines one nation's superiority to some (in some clinical cases - all) others and, hence, it only spreads hostility and enmity, it's mostly negative about presumed enemies instead of being positive about yourself.
Example of good patriotism - 'my country have/had great tradition in something and I'm really happy about it', example of bad patriotism - 'my country have/had the greatest possible tradition in something and all the others (or most of the others) suck hard being compared to us'. Many Lithuanians sadly still indulge in sweet memories how some win of Zalgiris over CSKA was 'the only way to beat Russians/Soviets ass' but for Russians it was just an exciting duel without their national pride being heavily dependent on that duel's outcome. Maybe, it was such just because there were tons of other, much more substantial than some sportive event's result, reasons to feel national pride without humiliating and confronting someone. Hell, I'll never get that but even nowadays many basketball fans from Russia feel sympathetic towards Lithuanian basketball and mostly root for their national team when it doesn't play Russia. Dunno why, maybe, it is due some sense of shared basketball history as some Sabonis is perceived as much less foreigner than some San Epi, heh, I don't even think that Sabonis is perceived like a 'real foreigner' here. I find this rooting for Team Lietuva among Russian bb fans really weird and I never was guilty of that myself but nevertheless it still is the case here. It is interesting how many Lithuanians root for Russian basketball teams, NT included
In fact, I think that Russian populace is not patriotic enough in many aspects

Their patriotism is often too superficial and shallow. Just like Lithuanian one - you know, all those Lithuanian 'patriots' who prefer to stay out of their home country on some British Isles and love Lithuania 'from the outside'

Not for nothing a process of steady population growth under 'brutal occupation' gave place to rapid depopulation of Lithuania once so-called 'independence' was achieved.
P.S. I'm often really critical about current state of affairs in Russian basketball and about many specific teams in particular. I would be the first to admit that in general Russians are big time chokers in basketball and most of the time we can't manage the talents we have in a proper way. But talents we do have in spades, most of them sadly get buried too early since big money in a poorly managed league can be also a curse for the development of local players. This is exactly the case with Russian club basketball.
