When I say submissive I am not talking about BDSM stuff where there are boundaries and it's all part of "roleplay". I am talking about people who want a traditional relationship with a submissive woman. I can't imagine how you can view yourself as a leader and not see the other person as inferior and I can't imagine how you can want to be submissive and not view yourself as inferior.

Let's examine what "submissive" means in this context. It means that you accept someone as your leader. You accept someone that is basically always right and you accept that you're always wrong because "they have the last say". In order to accept something like this you have to some extent view yourself as less capable , less smart , less rational. In other words you have to view yourself as inferior. And this puts women in a vulnerable state where they can be taken advantage of and abused.
