There is currently a troll on /prog/, and would greatly appreciate your help.

I'm wondering if the maths genius' on this board can rip him apart? Thank you

Mathematicians are truly the "copy cats" in the world. Think about, what do most maths graduates do? They either:
1) get a PHd and add some tiny, worthless new fact in the giant arena that is knowledge.
2) drop out see >>10
3) become elementary school/high school maths teachers, where they can regurgitate COPIED (STOLEN) information, where students can complete the cycle of doing either 1) 2) or 3)
They contribute NOTHING to the world. They are detached, sociapaths who's only shtick in life is being able to REGURGITATE some worthless, pointless little fact to try and impress people.
Attention:
YOUR PROFESSION IS WORTHLESS.
YOUR DEGREE IS WORTHLESS.
To paraphrase >>7
YOU'LL NEVER AMOUNT TO ANYTHING MORE THAN THE THEOREMS YOU MEMORIZE.
