What separates a man's preferences from an insecurity?

Have you ever noticed that when a man says the type of girl he's attracted to he's often called insecure or misogynistic? There's no alternative for women besides maybe gold digger or jealous? . For example I told my female friend that I like fit women (I'm also fit) and she told me that I'm being too picky and insecure, and when I told her it's just an attraction thing, and that out of shape women gross me out not make me insecure she didn't understand.
