Yeah, a lot of people mock LGBT activists for adding letters without seeming to realize that it’s harmless, and we make fun of it too.

LGBT, LGBTQ, LGBTQIAA+ etc are all sort of interchangeable. There are also about a thousand different pride flags. People keep adding new Pride flags every year. It’s all about self-expression, and not taking things too seriously. If you are not causing harm, violating consent, or excluding someone (which to be fair can be complicated topics), we’re a community that frowns on saying people shouldn’t do what makes them happy.
