Judging by your various edits you've made one thing pretty clear, and that is that no possible explanation Bungie could possibly give would be satisfactory for you. Here's the long and short of it. Lesbian, despite being a widely accepted term used by people all around the world is a world that carries a sexual connotation with it. It is a term used to describe a homosexual woman, and if someone were to tell you "Tokyo is a lesbian." you would probably be able to guess what I get up to in my free time, and you would also probably be able to guess that it's pretty NSFW. Now, with that being said, I would like to think that you're at least aware that your clan name is a bit more risque than the average clan name. It's not like your clan leader didn't know what they were doing and that this was a great big oopsie. It paints a picture and that picture isn't very family friendly, even if being homosexual is widely accepted and normal in most developed countries. Do you have every right to be annoyed? Yes. But your clan name is banned so you can either pick a new one or keep trying to die on this hill.
