I don’t really think you proved your thesis. Of course birth control was designed by men under the male gaze, because that was the society at the time. But since then, the pill has evolved and diverged and there are many, many different hormone mixes available now that still prevent pregnancy and treat other conditions (I take hormonal birth control because there aren’t really many other options to manage the symptoms from the cysts and fibroids I have in my uterus).
It seems that you’re angry at the world for not providing more birth control options when women already have far more options than men, and personally I believe trusting a man to take care of the birth-control is a pretty dumb idea if you’ve ever met a man. It’s not fair, but if you don’t want to be saddled with the baby, you have to take charge of preventing it.
