This one is just about dysphoria, something trans people experience regardless of the political climate

This one is just puns on the prefix trans-

This one just has a character wearing a trans flag sweater.

That all said, it’s probably impossible to post anything featuring a trans person without it being “political.” These also aren’t boomer memes for the most part, but I probably don’t have any of those in the first place. However, these should meet the bill of being mostly non offensive unless trans topics themselves are inherently not allowed.
