@hawkeye10,
It's not an insult, it's obvious. It doesn't take much of a brain to comprehend the obvious, clearly much more than you have.
If you took racism seriously you'd be horrified by one of your tea party spitting in the face of a Hispanic man. You're not horrified, you joke about it. Therefore it's fairly obvious to anyone who is not a cretin that you lot don't take racism seriously. You definitely don't, you use then word because you are racist, and you think racism is a good thing.
Be a man for once and stand by what you say, anything else is pathetic.
