The problems with this comic:
1) It libels George Zimmerman, who has already been found not guilty by a jury.
2) It's offensive to bronies, fedora-wearing atheists, fat people, and white nerds in general.
I do however agree with the points raised by the young black man in the comic.
And I do get pissed when white gamers use the "political correctness" argument to keep the medium as un-diverse and exclusive as possible.
As for white straight males being the only demographic that is still legally able to be discriminated against, it's true. You can relativize the importance of this problem, but you can't deny it's existance.
Again, this doesn't justify the actual discriminating crap minorities and women have to endure in videogames everyday, and it's our responsibility to make this medium as inclusive as possible.
Other than that, I laughed a lot with this comic.
If you think I am mistaken, please let me know.
P.S: If you get banned in this site, do they tell you the reason why? Something tells me I might get banned for this post..
