If you go against the norm of political correctness where it isn't warranted, be ready for the consequences.

It is politically correct to allow extra time for a senior to walk through a door way.

It is politically incorrect to push them aside. Not suggesting you'd do either. But someone who "rejects" political correctness with a weird brain might think, "I'm tired of waiting for seniors. Pushing them out of my way is what I think is appropriate, and that's what I'll do". In that case, the consequence is getting charged with assault or beaten up by an onlooker for doing something politically and morally incorrect.

So what I'm saying, is that when you said "why I must reject political correctness" might be too simplistic of a statement. It's a very touchy subject, as you see, one of us just got blasted by Hive account@shekelemberg for even "talking" about politically incorrect examples when it was only used for illustrating a point.

P.S. There are some gang-bangers who think it's funny to watch a senior get flung aside and get thrown to the ground. So it happens.
