I'm sure Scott Adams intention was not to make a racist strip, all types of comedy poke fun at everything from race to religion. Don't take it personally and certainly don't stop reading such a good comic!
I was a huge Dilbert fan -- until now. Not just because I'm Indian, but because I hate racists and chauvinists of any kind. Your racism has shown up before, but not so crudely and offensively. And I'm let down, because I've learnt to expect intelligent humor from Scott Adams and the Dilbert strip.
