I thought that's why you chose your name - because of Russian background in your family. It's certainly up to you, but that's part of your heritage and nothing you should have concerns over due to the current conflict. It's who you are.:smile:
There are hundreds of reasons you could have that name. I wasn't even 100% sure you had Russian heritage until today. Keep the name! If anyone takes offence at it (which I think is very unlikely) just PM them. If they still don't accept it, it is them with the problem and not you.
Nothing wrong with your name. Remember, in the last year much has been said about America's diminished credibility in the world, it's reduced "soft power." As a result, the difference between the rest of the world's attitude toward The American People and The Current American Administration has been highlighted; in Iran, for instance, the difference is huge.
The same would apply to Russia. Putin/Medvedev and their administration do not represent the attitude and opinion of all Russians.
