It isnt redundant because people dont follow "all" the tos rules when it comes to respect. Ive been in fc's where they still thought homophobic jokes were funny, used awful stereotypes to actively mock and when challenged was like "chill its just a joke" and made it my issue.

With my fc i do say it is LGBTQ+ friendly because that is what it is. But beyond that it has zero impact on what we do or do not do besides allowing people to just be themselves. I think that is the point. At some point, in the very distant future we wont need to have these kind of labels. But then i hope we wont also need to "come out" or be assumed to be "straight" until that day, well keep the notice on the door, so that maybe just occasionally we wont need to do the "am i safe to be myself" check
