have you considered joining a new server or creating one? if thats not an option probably the best bet is probably a newer server with a small over friendly community. probably not exactly what youre looking for but i doubt any server owner would post as a lgbtq+ only server since that would reduced the number of regulars the could get. If nothing else im creating a new server in the next week and would offer you to join my server.
i was actually about to create a new server also tell me what the base of your server is and maybe i can but that time,effort, and money i was going to put in my server into co owning or working on yours. Ive built three servers in the past so im very familiar with the process
