Isaac Hayes Hangs Up His "Chef" Hat; Leaves South Park Behind

The new episode was very funny, with many parallels to the Scientology episode and themes. I'll try to post with no spoilers, but anyone who knows enough about this story would have by now tried to see it any way they know how.

It's sad to see him go, but South Park will certainly continue, and the message at the end certainly clarified Matt and Trey's stance on the subject (see Watts' spoiler).
South Park is more about exposing hypocrites and social commentary than it is about immature humor, but the immarture humor is thrown in to keep the episode light and funny during the heavier scenes.
Imagery aside, the show won't end simply because Chef left. As stated before, he isn't a staple character and his role in the show has often been replaced by other characters.
There are plenty of things South Park can still attack, and what's stopping them from re-attacking.
Still, I hope they get off this whole 'let's all get scientologists' kick and get back to being good ol' South Park (minus Chef).

Oh, and just to enlighten some people, another of my favorite shows has a scientologist at its helm: My Name is Earl. Jason Lee is a scientologist.
Jenna Elfman is also one.
It's just a new celebrity fad. Very few of the people in it actually know its true beliefs because you have to pay in and involve yourself for years before you get to find out. South Park tried to expose it, but being so biased it's hard to truly buy in to either side of the 'argument'.
Still, as a rule, any religion where you have to pay to hear the beliefs and stories is sketchy, dodgy, and should be avoided.
