Politically correct film makers sanitized "50 shades of Grey": the heroine never submits, never surrenders. Movie heroine Anastasia Steele never enjoys the book’s spanking orgasm with Ben Wa Balls.

Anastasia Steele then immediately assumes the empowered feminist role, blames pervert Christian Grey and commands him to back off and not touch her.

50 shades of Grey is the deconstruction of dominance and submission. Rather "the heroine is tasked with transforming him from a tortured control freak and into a regular boyfriend ", says Slate. A feminist empowered Anastasia that does not submit to Christian Grey’s dominance.

Gays became a protected class, and thus can come out of the closet. Radical feminist like Valerie Solanas can promote violence against men. But dominant men with a sadistic streak must keep in hiding. Lest feminist boycott would ruin his business. Remember Dominique Strauss-Kahn.
Soldiers in boot camp, war, must submit to obedience, pain and humiliation
Soldiers routinely have to walk for days and nights, with bleeding blistered feet, sit in ice cold lakes. Boot camp pushes a recruit to his or her physical and mental limits. Without questioning and hesitation soldiers must obey, shoot, kill, and obediently run into a hail of deadly bullets. Often soldiers sign away their rights voluntarily (with no "yellow" or "red" safe word, with no right to back out!). For millennia most men had no choice; draft was mandatory. In the US men still must report to selective service to be ready for any potential future draft.
