Humiliation and subjugation are the only ways left to deal with women and the mess they have created with their ideas of independence, rights and equality; when instead it's their job to clean messes and be a mess when called for.
Even before the empire, women were collared and sold. It is only natural. So join your place amongst your sisters, and submit to the natural order. It is the only way to be truly free.
Women, fear not submission. It brings food, shelter, certainty, freedom. To resist the collar is to live a life of uncertainty and fear, with no guarantees. Come and embrace safety in the cradle of man, and we shall protect and guide.
