“Do you think my tattoo is cool?” No, I don’t. There are no cool tattoos. “Check out my sleeve!” Oh god ew.
Tattoos themselves are stupid. Doubly so if it’s some media IP. “I put Batman on my body!” “Look at this image of Goku on my calf!” I can’t think of many things I’d want to do less than that.
There are a few narrow exceptions. Chances are yours isn’t one of them.
If you personally like tattoos, fine. I’m not saying nobody should get tattoos because I don’t like them. I’m stating my opinion that tattoos are stupid, and I am stating it here because it is probably not a popular opinion.
Unpopular opinion on your opinion:
Stupid implies lack of thought on consequences or bad logic, which I don’t think applies to tattoos as they are (for the most part) an aesthetic personal choice.
Cool though? Yeah sure, that is a vague and subjective term.
So no, most (not all) tattoos are not stupid.
Counter point: many people get random tattoos that surely carry no meaning. Some tattoo parlors have quarter prize machines, where you get whatever tattoo comes out of it.
Plenty of people get tattoos without any thought towards the consequences. Thats why tattoo cover ups and removals are also a thing.
