Here's the deal. It boils down to a need to monitor what your children are watching. This show is aimed at the college community/upper-class highschoolers, therefore if you're youngins are watching it, where are your parental controls? You don't even have to be in the room, just use the remote! What else are they going to be watching on MTV, Teen Mom? Get real.
The issue of race is not the most predominant thing in this show,just a group of people that just HAPPENS to be comprised of some Italian-American's from Jersey.
Honestly, taking it as seriously as a lot of people are is just glamorizing the show, and being so adamant against it is driving kids to be curious about it and possibly emulate the show....
If the kid is not mature enough to know about s*x and drinking....probably not mature enough for this show.
If they do watch the show, just make sure to say you know they can do better, though it is good to have fun every once and a while... After all, it's not like Pauly and Vinny do nothing but outrageous, lewd antics every episode; though most of the comments about the behavior on the show aren't off base.
Don't take the show so seriously, that's giving it much more attention than it deserves. Maybe teach your kid to drive or something, they'd probably welcome some sense of independence.
