Expressing the actual problem, like this?

"See, my problem with political correctness is that I find it often is trying to hide an -ism."

That was the first sentence of the first comment I made. I went on to explain my point poorly, but that actually was my point.

I am frustrated that even after all this, you and others think I was advocating "throwing out the PC baby out with the bathwater".

I will work on being more sensitive, and succinct, in the future, to try to avoid these kinds of misunderstandings.
