For those of you who don't know what I mean, read a bit on Wikipedia about the infamous senator who inspired the term:
A quote from the article:
"Today the term is used more generally to describe demagogic, reckless, and unsubstantiated accusations, as well as public attacks on the character or patriotism of political opponents."
If that doesn't describe today's "Political Correctness", nothing does. Way to go, all you pc-pushers, McCarthy would be proud of you. Just remember, every freedom you take away from someone else you also take away from yourself. "You can't say that, because someone might be offended by it!" can degenerate into, "You can't say anything, because we said so!" faster than you might think is possible.
