the destruction of the Ukrainians as a people and culture
This is a huge part of Putin's current war; a war tankies widely support. You need sources for these things?

Of course they don't believe the piles of evidence. The point is they support the genocide either way. If we are changing the standard to purely what delusional people believe, not what they actually support, then there is a ton of people on the right we should stop bitching about, as they don't believe their policies are harmful either...
So, back to the original question, are you going to use a software written, or just partly written, by tankies? Or is it possible that one can use a software written by people who have differing political opinions from you?
