Now seems like a good time to repeat something I saw online that has become a mantra for me:
Just because one government is bad doesn't mean an opposing government is good
Specifically to US leftists: you can believe that the US is a bad, lying, imperialist nation and hold room for the idea that Russia also is a bad, lying, imperialist nation. "The enemy of my enemy is my friend" is not good long term analysis.
@darius, this must be extra difficult to overcome when in a culture with only two explicit, "actual" political options; one that celebrates the one v. one contest as the truest proof of power and value.
