Duplicity in offensiveness

During the 90's, I got a crash course in what is considered "PC".  Overall, I think a lot of it is crap, to be honest - I mean, some things are such idiotic pathetic attempts for personal gain than a true work towards a better cause that it just makes me throw up (just a little in my mouth).  However, there still is a place for being dilligent as to some words that can cause grief.

To that end, I learned certain words are just unaceptable, mainly words that are slang for races, religions, and sexual orientation.  Since that time, I've seen what a furor can arise over an inappropriate appropriation of such words.  What I don't get, though, is this:  why is it OK to use words for "God", "Jesus" or "Christ" in a flippant manner when those words are sacred to so many people?  Why is it that those words can be trashed and it's considered "OK"?  I mean, if the "n" word was used on TV the way "God" is, people would be up in arms. 

So, I'm coming out right here and right now and saying that I'm offended when any names referring to my God are used in that fashion.  Won't change who I'm friends with, but I think it's important to say, just as I'm sure you'd tell me if I was using language that was offending you.

Peace out  :-)
