I'm not clear what point you're trying to make. Nobody is lauding the opinion of self-promoting, self-interested douche bags. Trump is an entertainer - he wants attention and ratings for his shows and clothing line. Nobody cares what Susan Sarandon says any more than they should care what Trump says, when it comes to politics (or business, really).
Trump is a boob and the more he speaks, the bigger a boob he appears to be.
Just giving an opinion why people "taunt" her. I thought that's what you wanted.
Of course he's self promoting. Most of the ones who speak for either side are. Or else there be no speakers ever. Fine by me but that's the way it goes. Just don't point out Trump like he's the only one who does it.
