> political correctness has silenced important discussions our society needs to have
It would be interesting to know what are these "important discussions".
> 58% of Americans believe the political climate prevents them from sharing their own political beliefs
I don't think it literally prevents them, more like it makes them scared to share their political beliefs for fear of being called out when those are not "acceptable" beliefs. If anyone can give me an example of some political belief that is not justified in being "unacceptable", I'd be happy to re-evaluate this situation as being bad.
