What you refer to as the "PC-shit" are things that all point to real issues in our society(ies). We focus on certain things because there are problems in our society around those issues. Whether the particular measure or self sensorship or whatever is the appropriate answer in a particular case certainly can be debated. But behind those debates there are real issues around change, around social progress, around justice, around equality. It's not about a "majority way to think". It is sometimes about social pressure for certain changes though. And any time there is change there is resistance to change. Even if that change is needed.
