So, for example if Airbnb will deny access to black people, because there are violent criminals among black people in the US, you would support such policy, too? If no, I'd love to hear your argument why it would be any different.
You do make many emotional appeals, describing the untold horrors inflicted upon Ukrainians, and to make up for that you suggest punishing my friend who resides in South Africa and hasn't been in Russia for almost 10 years now. She just had her booking cancelled in Kenya.
I would add to the absurdity of your position the simple fact that among Russians travelling abroad, the support of Putin's fascist regime is almost non-existent. (it was high among Russians living abroad, who liked the idea of him projecting the strongman image, but people who really experienced his regime knew better).
