Nobody is saying what he said years ago wasn't disgusting. But it's not gross to see someone changing and becoming a better person and people being happy that he got his job back after the alt-right tried to perform a smear campaign.
The second half of your post was "and the fact that Feige fought for him. Fuck Disney." When actually it was Disney, and the Disney exec who had fired Gunn himself, that brought him back.
I mean yeah, if Gunn didn't love working with Marvel and doing the GOTG movies, he wouldn't be coming back...but isn't that obvious? What would he be coming back to if not the movie he was fired off of? lol
