I wouldn't call someone who is weak, meek or unlucky "losers." However, I do agree that political correctness is an attempt at social coercion. You should consider that, because frankly many points of political correctness reflect the viewpoint of socialists and atheists.
I agree that everyone deserves respect.
Yah. True. But not necessarily so - that's just the direction of modern-day leftist thinking. It began in the '60s when freedom of opportunity didn't lead immediately to equality of result. That's where the Lefties lost me...and a lot of others.
More generally, social coercion comes with every social system. Choose your poison.
