Look, the problem here is you are comparing bad with really really bad. People aren't defending the US via Russia here, people are saying don't defend Russia via the US.
Can you really imagine USA invading Mexico to extend its area of influence?
Facebook is filled with anti-US and anti-western arguments. VKontakte is filled with love for Putin. Apples to apples here...
Try to at least study history. The US has a long history of staging coups and invading with special forces Latin American countries.
My point is they are both so bad that saying one is really really bad is like Dante discussing why the third circle of Hell isn't as bad as the fourth. Pointless academic nonsense, except the jingoistic RaRa America nonsense is killing hundreds of thousands of civilians.
