Mark Ruffalo wrote a great defense of Joss Whedon and feminism on Reddit

On Monday, Joss Whedon quit Twitter after the opening weekend of "Avengers: Age of Ultron."

It was thought he quit after being hounded by threats and accusations of sexism. On Wednesday, Whedon denied those rumors. Yet, the accusations haven't quite gone away.

While holding a Reddit AMA about water defense, Mark Ruffalo, who played Bruce Banner in "Age of Ultron," was asked about the issue and came to Whedon's defense.

I think it's sad. Because I know how Joss feels about women, and I know that he's made it a point to create strong female characters.

Ruffalo says there are certainly problems with the superhero genre; however, those issues have less to do with Whedon and more to do with the system as a whole. 

I think part of the problem is that people are frustrated that they want to see more women, doing more things, in superhero movies, and because we don't have as many women as we should yet, they're very, very sensitive to every single storyline that comes up right now.

While Whedon may have quit for matters unrelated to this issue, Ruffalo says Whedon still thinks about it heavily:

I know what his values are. And I think it's sad, because in a lot of ways, there haven't been as many champions in this universe as Joss is and will continue to be. And I know it hurts him. I know it's heavy on him. And the guy's one of the sweetest, best guys, and I know him - as far as any man can be a champion for women, he is that.

Ruffalo has been a vocal defender of Whedon on Twitter as well. Here was his response when somebody asked him about "internalized misogny" of making Black Widow the love interest:

I think it's sad. Because I know how Joss feels about women, and I know that he's made it a point to create strong female characters. I think part of the problem is that people are frustrated that they want to see more women, doing more things, in superhero movies, and because we don't have as many women as we should yet, they're very, very sensitive to every single storyline that comes up right now. But I think what's beautiful about what Joss did with Black Widow - I don't think he makes her any weaker, he just brings this idea of love to a superhero, and I think that's beautiful.

If anything, Black Widow is much stronger than Banner. She protects him. She does her job, and basically they begin to have a relationship as friends, and I think it's a misplaced anger. I think that what people might really be upset about is the fact that we need more superhuman women. The guys can do anything, they can have love affairs, they can be weak or strong and nobody raises an eyebrow. But when we do that with a woman, because there are so few storylines for women, we become hyper-critical of every single move that we make because there's not much else to compare it to.

So I know Joss really well. I know what his values are. And I think it's sad, because in a lot of ways, there haven't been as many champions in this universe as Joss is and will continue to be. And I know it hurts him. I know it's heavy on him. And the guy's one of the sweetest, best guys, and I know him - as far as any man can be a champion for women, he is that.

So it's been a little disheartening.

But I also see how much people love that aspect of it. There's an equal amount of people who find the love interest between Banner and Black Widow to be a big standout. And it's very satisfying to people. So it's a movie. People are going to have their opinions. And that's actually a great thing. The fact that this is a debate that's coming out of this movie is probably a positive thing.

I just don't think that people should get personal with Joss, because he really is - of anyone - an advocate for women. He's a deeply committed feminist.
