I understand how comments like yours and other sibling comments will generate feelings of being treated unfairly: We do not choose our birth country. We do not know the individual's actions, we do not know their political stance, and it is not racist but still discriminatory to use their nationality against them. They're already punished enough by being associated with their government. That's at least how I see it.
Then again, it is probably due to EU wide legislation, so not something Estonia can do much about even if they wanted to. I hope they find emotional support to detach their individuality from how Russians (and Ukrainians!) are treated in general in the current dynamics. It's not their fault as individual, and I'm sorry that they became victims.
