Tattoos have a very different level of commitment, and neither need to be anything more than decoration or affect you. They can be vaguely amusing, totally innocuous, slightly differentiating for practical purposes, all kinds of things. I used to have an "I <3 Beaver" sticker on mine, no need to overthink it.
It's got the same vibe as going into a circle of people having fun and telling them they're trying too hard. What's the effect you're going for?
You're not being stopped from having an opinion - your comment is visible - but sharing one that'll only serve to bring down people's moods makes everything a little bit worse I think.
If you're in a circle of people whose moods can be brought down because of a shared opinion, you're in a circle of prepubescent children who haven't learned to regulate their emotions like a grown up.
