Honestly, people who post rants or whatevs on YouTube should really sit down and consider what they want to say first. They just whittle on about the same point over and over again as they try to think of the next thing to say.
Also there is something very off putting in someone saying that everyone should have the same opinion as him. No matter how valid your opinion is, you don't have the right to say that this is the opinion everyone else must have.
Also it's funny that in all that time they didn't actually come up with the sound logical argument for heels. When one jumps you launch off the balls of your feet. If one's feet were propelled at great speeds by a rocket you'd basically want to avoid your ankles having a discomforting jolt every time this happened so to avoid this you'd want your feet in a ready to jump position. Hence heels.
