Yeah better discriminate based on nationality /s. But why stop at that? Poor people are too easily bribed can’t have them. I hear the CIA recruits from top US universities, can’t trust those college grads either. Anyone belonging to some homophobic church or religious group? Better not what if they’re closeted gay and get blackmailed? Anyone in a monogamous relationship should be excluded for the same reason, if you think about it. *tips forehead*
We stop at that point. Because it is very clear and obvious to everybody, that a Russian citizen can be forced to do the governments bidding at any time and Russia has demonstrated that they will do that. The whole country is build on propaganda and fear amongst it’s people.
The rest of the groups you name, are not the same. Sure, a poor person could be bribed. But is that the same as the 100% chance that Russia will use anything they can to fuck with everybody they see as an enemy? I don’t think so.
So your arguments are simply invalid in this case. If Russia was a democracy, a real one, I would say they made the wrong decision by pushing the Russians out. But in the current circumstances? I understand the decision.
