Well, using the term isn't the same as admitting that it's a genuine problem. The way Gage is talking here, I can believe that he perceives her to have been mistreated, but that doesn't mean that the general Marvel braintrust agrees; knowing "the fans call it a fridging when we beat gratuitously on a female character" and joking about that in an interview doesn't automatically translate to knowing "gratuitous abuse of female characters is problematic and we should stop." Just because an atheist knows the language of Christianity enough to use a phrase like "oh, this chocolate is heaven" doesn't mean he actually believes in an afterlife.
