Because, after 19 season, I'm inclined to believe that's what Stone and Parker actually think.

I'm putting it into perspective. Are you criticizing it… while doing it?

-HEY I'D LIKE TO VOLUNTEER TO KICK YOU IN THE VAGINA WHERE DO I SIGN UP?
-YOUR DAUGHTER HAS A MUSTACHE - WHAT THE HELL IS WRONG WITH YOUR OVARIES, BITCH?!
-YOU'VE BEEN DICKSLAPED!

I don't think it's pro-troll, it just criticizes the anti-troll panic. To me, the message is not that trolling is good, it's that is bad but not a big deal.

That's not what Gerald does. And I don't even think it qualifies as "trolling".

The disappearance of Cartman is from social media, not real life, and it's only going to last until his next birthday or christmas. The drama of the scene is used to show the difference between something serious (a murder) and something that's not a big deal (a few month off the internet).
Likewise, the girls breaking…

"It’s tempting to read all of this as an endorsement of trolling, but “Skank Hunt” makes a point to show how cruel Gerald’s actions are—his all-caps remarks zipping across the screen for the audience to see."

I know it's sarcasm, but it's nonetheless true. Aggressiveness is an absolutely necessary trait for a civilization. Peaceful civilizations gets replaced by aggressive, expansionist ones.

Why is it a problem if videogames (or any other media) emphasize female butts? The problem is obviously not discrimination, because "the answer is not more male butts". Than what is the problem?
