Different wikis have different rules. Wookieepedia's discussions are strictly on-topic, and that post wasn't. It wasn't anything to do with the post being about Pride, they delete/lock any off-topic posts.
Other wikis have different rules, and you could tweak your question to be more on-topic. But I would say the best place to ask about general LGBTQIA+ characters is the LGBTQIA+ Wiki 🏳️🌈 or the LGBTQIA+ Characters Wiki. It would definitely be on-topic there, and there should be plenty of people on those wikis keen to talk about their favorite LGBTQIA+ character
