This is, for example, what I get when I search for “anti-conservative t-shirts” (if it’s too tiny, try it yourself - they’re all anti-liberal):

You make your point well. I just wanted to point out I believe at least one of them is anti-conservative (The devolution of humans into the GOP)

And one is possibly unintentionally anti-conservative: If Liberal Perspective is actually a liberal’s perspective the subject is a conservative with their head up their own ass. I don’t believe that’s the shirt’s actual intention though. It would be hard to depict the interior of the rectum on a T-shirt
