I think at the end of the day it is moralism. They have a deep, deep seated hatred of Russia and Russia is always evil and bad to them. That colors their judgment and makes them take the incorrect stance, when they may otherwise have seen the truth clearly (Compare support for Libya or Palestine, which few here would oppose, to support for Russia. All of them are capitalist nations being colonized and attacked by imperialists, but only 2 of the 3 get any type of critical support… for some reason)
