maybe if the cosplayers stopped being treated in such a way it'd help?
These guys actually are a real problem because the way they approach women is "we're going to ask you a few questions about the convention and your costume, is that okay?"
I have seem women storm off completely upset from their interviews before, and they still ended up using the footage from before she stormed off in the final video. These guys are just assholes and should be shamed because it makes everyone hesitant about participating in actually well shot, well cut, well edited con montages.
