re: "So you're saying that if I own a business and I discover that an employee of mine has CHOSEN to change his religion to one which I object to that I'm allowed to fire him or her, correct?"
Incorrect. You just made up a bunch of garbage and attributed it to me. Believe me, if any of that is what I'd intended to post, I would have done so.
It is not illegal to discriminate. Period. When you said that it was, you were wrong. If you think otherwise, please provide us with a link. (And you won't because you can't.)
I'm free to discriminate against anyone I like, and so are you, EXCEPT IN SPECIFIC INSTANCES.
Now, I put that in bold this time for a reason, OCU. I trust you will remember it the next time you wonder whether whatever you think I mean is what I actually mean.
