to propagandize for the left. They all know it. The ones who don't are required to maintain constant vigilance that an errant opinion doesn't slip out.
Look at even the b-grade actress who stood up and supported Romney last election. Universal and immediate firestorm of hatred from her community, and she wasn't even a big enough star for America to know more about her than her one role as a sidekick in a rich-girl teen movie over a decade ago. If the community goes to those lengths digging up a nobody just to publicly crucify them, you can bet they will end practically anybody if they can. You literally have to be Clint Eastwood status not to get steamrolled.
