I've slept on this now, and while I still apologise that you feel you have been gaslighted, I can't agree. I also don't agree with your stance on objectivity.
While it would be lovely for morals to be objective, and certainly easier to impose on others, they aren't. Morals change and are fluid according to the social norms of the time and culture. Equality between the sexes is not a moral issue, for me, it is a social imperative.
Anyway, over to far more knowledgable people than I on the subject. A few ethics lectures probably doesn't cut the mustard when it comes to this sort of thing, and the best thing about this board is the constant learning experience. Well, that, and the virtual companionship of some amazing women.
