Wow one article nailed all four of those. Yes apparently Iron Man 2 was sexits, racist, homophobic, and bigoted all in one movie (how do they get all of that done in such a short time span). Larry Correia, author of Monster Hunters International, took the accuser to task.
Seriously it’s hilarious (Mr. Correia’s commentary not the original writer of the dribble).
Also if you go to a super hero movie realize two things: it’s going to be over the top unbelievable and shit will blow up. It’s entertainment, try to enjoy yourself instead of be angry.
