Just saying someone can view it that way without being a troublemaker. If it bothers them it bothers them; what you should care about is whether they impose that bother on others.
Yes, absolutely. And to clarify, because again I still don’t think of it in terms of zero sum, I don’t like BitD overall but that doesn’t mean I can’t still find a way to have fun. I like the group I play with, I’m a good player, and I know how to create my own fun within pretty much any game system. If those didn’t apply, I’d excuse myself.
But getting back to the overall point, I don’t expect a rule in a book to have to tell me that’s the way to act.
