What's in a Name?

Here we go again.  Someone went and degraded millions of people by using a taboo name.  I was reading today that Jennifer Aniston is catching all kinds of hell for using the R-word (retard) while self-deprecating during an interview.  Seriously?  I mean really?  Using a term that, yes, can be degrading toward those that are mentally challenged when directed toward those persons, but to demean yourself is now off limits?  Come on people!  Are we so concerned with everyone else and what they say that we hang on every last word that comes out of their mouths and then analyze every minute detail of it to the point that we can now demonize someone who was essentially making fun of themselves?  Give me a break, people need to quit being so sensitive about everything.  I personally don't condone using stereotypes or derogatory words towards an individual or group of individuals, but this, I feel, has been blow WAY out of proportion.....just goes to show you that there are people out there that have nothing better to do with their time than to make a fuss when someone says anything that they feel is inappropriate.
