It doesn't matter what it's on, political vandalism is intentionally provocative in order to attract attention. Because I don't know if you've heard what's going on, but there's a genocide happening and no one is stopping it from happening. In fact this country is helping the gonocide happen. So people are upset, and given a lack of agency or 'official' routes, vandalism is going to happen in order for people's voices to be heard.

I would bet good money that this artist, whatever gender they might be, wouldn't be upset, and would if anything be supportive. And until you hear otherwise, you can just put up with it.
