Politically correct speech is all but mandated by our culture. But the great irony of people who defend p.c. rhetoric is that they are some of the most hostile people out there. They want you to be ultra sensitive to the feelings of others. But say the wrong thing on accident and they will attempt to ruin you. Never mind what you are feeling.
Maybe instead of obsessing over political correctness people out to learn to use common sense in their conversations with others. Speak the truth in a loving manner, don’t assume the intent of the other person’s words, and exercise a little humility when you disagree.
