Well, I can only comment on my social group and that is the only group i am concerned about in this context. So, it is 'most people' for me.
If your behavior can at all be described as sexist, then you're not a feminist.
I hate this polar thinking so much. Everything is not all or none, yes or no, black or white. People are unique and everything is a spectrum. Even Hitler had admirable qualities and if this makes you uneasy, you need to open up your mind.
