-Sam Wilson, the current Captain America, fights the Sons of the Serpent, a group of extreme right-wingers who use violence to stop Mexican workers from migrating across the border.
-Right wing outlets see the scene, a scene featuring a group that's Marvel's version of the KKK, as one that's attacking them and their conservative values. They also claim that Cap is now fighting conservatives as seen here.
-Nick Spencer has been receiving death threats for the issue and there's a change.org petition going around that wants him off of the book. His response:
More than anything I'm just amazed how certain media coverage of Sam Wilson: Captain America #1 directly mirrors what we showed in the book.— Nick Spencer (@nickspencer) October 19, 2015
I love how this book and Batman #44 made conservative fans mad tbh.
