It seems to come up every time this complaint arises. "I want to use an open source project without being associated with furries" isn't that unreasonable of a request.
There is a difference between some maintainer somewhere being involved in a subculture and graphics from it being the first thing you see when you visit an unrelated website.
My problem is more that I don't want open source infrastructure I don't control to be infected by this. For my own website I can just make it efficient enough not to need hacks like this.
