You can decide all clovers have 3 leafs. That doesn't mean 4 leaf covers stop existing or are wrong.

You can decide "but" is only for contradictions. That doesn't mean people won't use it other ways or it's wrong.

You can decide all men have penises. That doesn't mean some won't or that's wrong.

You deciding shit doesn't actually change reality. And being pissy about it is as idiotic as suing 4 leaf clovers for you thinking they should only have 3 leafs.
