I think a lot of the problem arises because MRAs mostly just talk about issues to shut down feminists. Like the latter says something and they pipe up "but what about homeless men". If they'd shut up and just get on with actually helping homeless men rather than using them as a point scorer, people might be more sympathetic.
Anyway, you might want to explore "toxic masculinity". Often phrased as a problem for women, however, I think boys themselves lose out from it just as much. E.g. school performance: girls are chastised for misbehaving for having bad grades, so they study more, they behave. On the other hand "boys will be boys" and so boys don't learn to take school seriously (obviously these are generalizations that don't apply universally). There some evidence that girls do better in academia because they are better at following instructions. For example, more women in call centres, because call centres have instruction (to be crude one could say "girls are meek and compliant while boys are rebels") manuals that women follow more strictly. Flip side is that this means boys are bigger risk takers and might try things, and later in life, some of them become more successful for it. Bottom line, gender stereotypes hurt boys just as much as girls. I think that's something you could include.
As an aside, you need to present alternative viewpoints. Especially in this day and age on this topic. It sounds like you are very supportive of this movement, which is fine, but don't forget to put in critiques, too, and alternative views. If not, I would bet your grade might suffer.
