Sometimes it can be helpful to be in a space with people who might share similar experiences. A lot of queer people experience rejection by their birth families and having other people going through the something gives them a new support system. Those organisations often have specialised therapy available and resources that can help.

Of course you shouldn’t feel pressured into a space you don’t feel comfortable in but your comments all seem very pointed and angry about other people’s celebrations. The world can be a dark place and I also hate rainbow Capitalism but that’s all the more reason to support small queer businesses and throw your own celebrations with friends.
