Louis C.K. has already been mentioned, but it deserves repeating since he will go down as one of the greats just on the fact he has a new special every year. Of the current crop, Anthony Jeselnick and Amy Shumer are excellent (though they are certainly PG-13 at the least. I also probably misspelled his name but I don't care to google it on my phone at the moment.)
Mitch Hedberg would be a 90's staple that I'd recommend if he's never been seen before.
However, in this day and age, you're going to find it nigh impossible to find a good stand up who doesn't make fun of something that you value, religion, race, sexual orientation, politics, etc. Best to just watch and realize, it's comedy and nothing more, and more than likely the ones making fun are more tolerant than any of us ever will be.
