What happened to the practice of conversation and the art of debate?  Why are certain topics off limits at all times? For some reason we are no longer happy with a simple exchange of information and learning from one another; now someone has to win.
Political correctness, self-importance, ignorance - cast these things away.  Research what you do not know, trust and ask those around you for their thoughts, and accept that you may be wrong.
Conversation is not a competition, but an opportunity to learn.
