They are bennies with cat ears called pussy hats, not "clit hats". They were made in response to the "grab me by the pussy" remark The Donald made.

Also AFAB people have a right to destigmatize their reproductive organs. (Think about how many times a day middle school boys draw penises on things)

Now that being said, I think the pussy hats are problematic because they are trans exclusionary, which is totally unrelated to your imagined feminist hypocrisy.
