This week saw Marvel Comics change up the origins of Captain America making him having always been an agent of Hydra.
While Marvel Comics did it because DC Comics released their huge Rebirth issue, and we know it will eventually change back, fans are pretty upset.
"If you're a forty-year-old dude claiming a comics company ruined your childhood because of a plot twist, you might consider that your childhood really wasn't that great to begin with," Gunn posted, which has caused fans to erupt in the comments.
While at first Gunn honestly comes off as sounding like a dick, in those comments he follows up with more explaining that his opinions are aimed at those Captain America fans that take things a bit too far (such as death threats etc).
"I didn't stick up for the plot twist. I just said if you're giving a plot twist so much power over your life, there are deeper issues at play," Gunn added.
Gunn continued with a reply to a comment that notes most of the complaints are probably coming from fans that don't even read the Marvel Comics (compared to the movies not many actually read comics).
"And the MCU is not the same as the 616 so they can do what hey want," Gunn said.
Gunn also responded to a fan's comment that changing Captain America essentially into a Nazi is a slap in the face to the character's creators, two legendary comic book figures who are Jewish, Joe Simon and Jack Kirby.
"I think saying something so trite is a slap in the face to the creators is a slap in the face to the creators. Simon and Kirby's lives and works are a lot bigger than this one issue of a comic book. This argument seems like it's reaching for a reason to be outraged as well as being a rather offensive exploitation of Joe Simon and Jack Kirby's very real struggles," Gunn said.
Gunn then joked his own childhood was ruined by Cap Wolf.
"Marvel ruined my childhood by making Captain America a wolfman," Gunn said.
