Don't take this the wrong way: While I agree that in some cases (other than this) sexism is a problem. But these things are not big issues, and the fact that you made a 15 minute video about it shows that you really do care. So please, don't be that person that is constantly concerned about how "everyone is equal" because in all honesty, there will always be people that will be jerks, and that's part of life. There are a lot more things to worry about than people saying a few nasty things to you. Nobody is discriminating you.
