I bet since Marvel has the rights to the Alien and Predator comics from Dark Horses that they're gonna edit all the swearing and probably even water down the gore too since Marvel is basically for kids and for us adults who grew up in the late 80s into the 90s collecting the Alien and Predator comics from Dark Horses.
I see this a lot online and it only proves to me that nobody is actually reading what they put on shelves. Here's a few examples of what Marvel does to an Avenger every month.

Aside from that and how Xemnu eats, over in the Spider-man books they had Carnage ripping people's spines out and when he wasn't doing it his buddies (one of them a deformed Spider-man clone) was doing it.
Hank Pym (currently Ultron) also now lopks like this)
I think I have enough images so to sum up why the gore statement is dumb. But aside from that, Deadpool does this shit on the regular and Captain America was recently replaced with a Nazi doppelganger of himself who'd been CAPTAIN AMERICA for about a year or so. The violence is present and Marvel despite being owned by Disney is ballsy enough to do this and all the images here are from books more or less within the last 5 years or so.
