Creating Feminist Male Heroes

I came across this blog post while researching more on writing: http://kancrum.com/post/78193898068/writing-feminist-boy-protagonists
This blog post comes from an author, who shares their thoughts on creating protagonists that are feminists.
What struck me about this post is how nothing about their list is about male characters engaging in feminist discourse, nor is it about male characters speaking feminist theory or rhetoric. Instead, this is about the character trait used to construct male protagonists as people. I think this is immensely valuable.
Yes, being able to engage in discourse is useful, but when considering the landscape of fiction, especially fiction for young adult audiences, it's also important to consider how characters behave and present themselves. My first reaction to this blog post was that nothing about it was inherently feminist, yet upon further consideration I realized that yes it is.
When considering the landscape of fiction, male heroes follow a few general stereotypes, and we can find plenty of examples of toxic masculinity in media geared towards men. Video games and action movies have plenty, and when we consider this, we can see that there aren't many examples of positive male role models for young boys to be found in media that is specifically targeted towards them. In which case, subverting harmful tropes such as aggression, coldness, misogyny in male characters will help change the landscape. If we endeavor to show that there is more than one way to be a girl, we should as well provide boys with alternatives to normal masculinity, and show them that there are other more healthy ways of being a man. If we can associate more positive traits with masculinity by portraying boys differently, then maybe we can help undo the damage of toxic masculinity.
