You and the rest of your lefty bed wetting friends are free to think and say what you like but it doesn't mean that you have to be given a forum for it.
As for your tough talk it's just that. Talk.
If you think you're so tough show up at Rolling Thunder and try to burn a flag. I guarantee that whether you bought it or, more likely, stole it to be burned that it comes out of the ordeal better than you.
