I'll be honest...I wouldn't recommend actually posting this to your youtube. When you make videos like this, it just validates and encourages your critics, many of whom are simply just unhappy people that want to make others just as unhappy.
It's an unfortunate thing, but you're never going to satisfy those critics. Every youtuber has them, and it's not something you can fix. When you acknowledge the criticism, especially the *ridiculous* criticism that's based on stuff like your looks, whether you wore makeup, and whether they think you actually birthed your kids, all that's doing it *highlighting* that criticism and giving it a veneer of legitimacy.
This is sadly one of those things where you really just need to ignore those idiots. It's an unfortunate reality that there's simply a body of people in this world that just innately hate it when a woman is successful and especially when a woman isn't *ashamed* of her womanhood.
Really, I think this video, if posted, would do more to encourage rather than discourage those types of critical comments, because they'll know they can get under your skin with them. >.<
Edit: also, do *not* cave on your wardrobe or looks. Those are *your* choice. If people don't like them, there's plenty of other content channels out there. You shouldn't (and shouldn't *have to*) sacrifice who you are and what makes you feel good and confident and strong just because some people think women should be concealing every hint of their female shape. When you open the door to changing your style and looks to suit your critics, you lose every inch of control over your image and content.
