It's pretty simple. Drunk driving = wrong, and he should be arrested etc. Of course people are more interested because of who he is. It was just a mistake, but one that he should have to pay consequences to just like anyone else.
Sure, have a drunken tirade. I do it all the time m'self!
But seriously... drunk or not, if you start going off about how 'everything is the Jews' fault'... yeah. You're an anti-Semite, and for that kind of irrational racism, you should be bitchslapped. I believe in free speech, but I also believe in bitchslapping.
