Because you have to be so deep up your own ass to purposefully ignore information about the atrocities committed by your country, that you could probably see the light through your mouth.
I sort kind of undertand brainwashed russians living in a russian bubble, with no access to outside information. Fine, you're fed shit all your life, so that's the only desert you've had and that's the only desert you want/need.
But this moron is out in the free world, and simply cannot underatand why, oh why could people be weary of russians? Truly the pinnacle of evolution.
