How else can a bunch of very different people work together and be productive together without some level of decorum and safety? So, we get rid of 'political correctness' (i.e. respectfulness), and what then?

Many people don't like their co-worker's or neighbor's personal beliefs or behaviors. I can't see that letting people be persecuted openly will end well or fruitfully for anyone.

Addendum:

It's interesting that my other comments are getting downvoted or even detached. Wasn't part of this big 'movement' to get rid of political correctness? I guess I don't understand. But, I'll be done. Sorry.
