When going to your movies and concerts mean you turn around and spend your mega billions to endorse your political point of view at my expense... hell will freeze over before I see your movies or go to your concerts. You "celebrities" better hope against hope that my sentiments aren't contagious. Meanwhile, I am hoping and praying we the people black ball you over paid big mouths.
The notion that you believe Ben Affleck is a good actor, much like the contention that "Ichii the Killer" is a cinematic masterpiece, is something that cannot be dislodged from a person's mind through either subtle or overt intellectual appeals.
The person who likes Affleck's work simply has no aesthetic judgment, and there's not much that you can do to change his or her mind.
