Preach it, brother!  I, too, am tired of this rush among professed Christians to embrace PC language. It is indeed ludicrous.  In their blind race to be just like the world (well, like the left wing fringe, anyway), they've forgotten that in "humankind," there is "man;" in "chairperson," there is "son;" in "spokeswoman," there is "man," etc.  Sorry, man haters, but that's the way it is.

My town has "manhole" covers, not "person hole" covers.  "Humankind" is one of the worst innovations of the PC movement.  It's awkward, for one thing, and fools no one.  Anyone who has studied the Bible, knows that when it says God created "man" it means mankind; and when Jesus said "Man shall  not live by bread alone . . . . ," He was referring to the entire human race.   Unfortunately the activists in the PC movement are good at feigning shock and taking offense at any perceived slight, usually when none was intended.  They see sexism around every corner, just as race baiters see racism everywhere.
