Just make a rule that transphobes and other bigots will be banned like everyone else.

And how do the mods find the transphobes to ban them? They’ll have to wait for an argument to happen and someone to complain about it. Waste of everyone’s time. This way transphobes will get triggered when they try to sign up, throw a tantrum, and get banned. That’s the plan; I have no idea whether it works in practice.
