Anti-trans works as an adjective in this sentence, so it is a ban that is anti-trans in nature, not a ban of anti-trans behaviour.

Your commiting a logical falacy believing that a double negative automatically means the same as no negative. “You are not allowed to not run” doesn’t mean that you are merely allowed to run, it means you must run.

Buuut again, I assume your logic means the downvotes to your comment acts like a negation to your comment and so I’m not sure what you meant.
