I do it all the time; it's just worse when hypomanic (I'm type II). I think I have a couple of different things going on. I am bad with boundaries and taboos all the time; why I cannot seem to remember to think through "da' rules" when in conversation I don't know. I am not bothered by talking about things that others typically are. I will ask people questions that are rude. My LGBT friends tell me I am the worst allie ever. When hypomanic, the arrogant jackass comes out to bray. If someone is offended and tells me or I notice from the reaction I apologize (unless I am really hypo), and I mean it. The unfortunate effect is that it makes it difficult to make new friends.

I am not sure that is any help other than to say you are not alone.
