I speak Russian and have known many Slavic women, some of whom were professors and teachers who scared the hell out of me. Lol!
My first thought reading your title was, These men need to meet real Slavic women who grew up learning to overcome adversity and not tolerate sexism.
I know things are more complicated than that, that Eastern European women can face serious problems that leave them vulnerable, but the stereotype of submissive Slavic women is just so ... ridiculous.
I'm glad you're putting that message out there so strongly.
