I wouldn't mind not seeing any of those userboxes on the projects, but... userbox wars have wasted countless hours over the years. I was tangentially involved in debates about the pedophilia/ephebophilia boxes, the "User supports Hamas" (etc.) boxes and a few other debates, and found that only the most universally reviled boxes or boxes no one actively uses can be deleted without triggering a major storm of drama.
So while it's worth asking people what they think about the userboxes, they should also consider how much time and effort they think it is worth to try to get rid of them (if that is their preference). Since there is no higher authority to declare them forbidden, you'd have to slag it out over each and every one (or at a minimum, propose slates of them for deletion and then bear the slings of those demanding they be split out into separate debates).
