Should we allow/create tags for well known Woo-woos and snake-oil salesmen?
They all have a proven track record in unsubstantiated claims and being able to cross reference question would be useful.
I don't mind the idea of tagging names for commonly-mentioned notable people.
But we should be careful about saying that they are Woo-woos, because that is an ad hominem attack. Jenny McCarthy's next idea needs to be considered on its own merits.
I think so. If they're very active, like Jenny McCarthy is, then there will be people who will want refutation of their newest arguments.
There are notable pseudoscientists, who originate bogus theories, and there are notable celebrities, who make existing theories more popular. I think they're somewhat separate.
