Stan Lee has always been a SJW. If you knew anything about him, you'd know that. Its not a slant, it's what he and Marvel have always been about. So you might want to either get used to seeing it, or not go to anymore Marvel movies. God forbid you read any of the comics these days, your head will explode.
I mean, how could you read something like X-Men and not get that? Spider-Man? Powerman? Black Panther? In the 60's and 70s, a lot of the stuff in the comics was definitely groundbreaking.
BTW, box office as of today:
Black Panther (2018) - Box Office Mojo
Over $700 million worldwide, with over $400 million in the US alone. Guess people respond to that PC/SJW stuff more than some of you might like.
