GLBT children of well known right-wingers are either outed or just plain covered in the mass media more frequently than GLBT children of not-so-well-known right wingers because our culture is sick. I mean, let's face it, our culture gets off on the titliation of the "deviant behavior" of children of famous people as a rule.

Most likely, the children of well known right-wingers are GLBT in the same porportion as the rest of the population. It just gets promoted into the public consciousness more.
