Not necessarily (though of course possible). In germany we have lots of people of russian descent. While amongst the younger generation some (not all by a long shot) may be more west oriented, the older ones are usually only consuming russian national media and dont like to engage with german media at all. Thus some people can be influenced to be aggressive towards ukraine. I have seen ukrainian flags ripped off and a glas display for ukrainian refugee support being shattered around the area where the russian descendants of our city live. While in my case that isnt much, It certainly shows aggression. But i also have to say that most are peaceful. It does however exist in a minority.
Some of them have been living here for a long time and have contributed to our society. Assuming all of them to be bad people is just flat out wrong.
I understand the disapproval of what is happening right now. But i too have russian friends who are completely opposed to the war and in some cases try to help ukrainians who have to flee.
