You're free to have a toxic, noninclusive community. Setup a login window in your discord server that clearly states "This is a toxic, transphobic, homophobic, racist, etc community. By clicking the Agree button you forfeit all rights to being treated with any form of respect and acknowledge you may be attacked, harassed, doxxed and threatened for any reason at any time. If you complain in any way shape or form, you will be immediately blocked without warning."

You can use mee6 to set that up and enjoy your toxic and non-inclusive community.

The absence of any such login window implies that a basic social contract is followed, which this community is clearly in violation of.
