Do conservatives mock ALL celebrities, or just the liberal ones?

They'll rant against Rosie, Sean Penn, Susan Sarandon, Ben Affleck, Jon Stewart, and Danny Glover, but seem mute or favorable to Ronald Reagan (chimp movie star), Charlton Heston, Tom Selleck, Dennis Miller, and Ted Nugent. Maybe it's not so much the Hollywood/Rock'n Roll ociation, as it is they just hate anyone who thinks differently than they do?
