I understand wanting to protest the war, but this seems like a dumb way to do it.
It's like bringing a deer carcass into a vegan restaurant - it's rude, uncalled for, it tries to force something antithetical into the community, it's almost exclusively done for selfish and narcissistic reasons, and the people who do this sort of thing tend to have zero awareness of what they're even bringing to the table or how much of assholes they're being.
Political stuff should be banned already. It's always shoved in, in the most obnoxious way, and any critic about it is met with a "oh so if you don't like the picture that means you disagree with it, therefore I win" comment.
