(Reality Posting)
I stated how i figured it in the post you quoted but let me get more granular for you.
I believe this is a very sensitive subject for alot of people because it stirs up so many emotions that makes people have circumstantial logic. I also believe because so many black men were raised by women and think like women some basic concepts shared by most men on earth escape them.
To put it simply, I dont believe everything that men do, women should do. Most men believe this but have their own preferences on what they feel both men and women should do. I dont believe women should be whores just because ive put the dikk to so many beautiful women. I wouldnt want to date a woman that had as many sexual partners as i have had. I wouldnt want my unborn daughter or son to experiment with the drugs ive tried. Sistas accept two men grunting together in dookie sheets more then a brotha with a non-black woman. I dont believe in do as i do. If i were a janitor, i would be disgusted if my child wanted to mop cac floors for a living but again, thats selective preferences. These are just MY beliefs.
That said, because of the power dynamics beween men and women, i believe black women are largely subject to the culture of the men they marry and have children with. I believe this is proven by the histories of the middle east, south america, and various islands around the world. Men take the women of another race/culture, and turn them into a variant of themselves, culturally and biologically and these groups of people work to the benefit of the culture of men that created them.
African women largely did not convert arabs to african culture. Indigenous Americans largely did not convert colonizers to their cultures. Black women in the phillipines did not convert asian men and spaniards to the culture of their islands but the children they created all worked for the glory of the fathers group. These men do not exchange women with the men whos lands they conquer. That would have changed everything. Instead, Its one way. This is why i believe that black women Especially, should avoid dating interracially and all efforts for them to do so should be hated on, spoiled, ruined and destroyed by black men. Ive done it in my family often and all the women in my family are with black men since only a black woman can birth what would be called a (pure) black man.. Its not fair, and i dont care.
I believe black people collectively should avoid serious interracial relationships because of extreme cultural differences and white supremacy which has created racism. These two factors lower the number of people available to both men and women for equally healthy relationships in my beliefs but overall, its easier for men to take women from other races/cultures because the nature of women is to Follow the lead of Men. If you choose the wrong woman/man you not only have external forces to deal with but forces within the family you've married into. If you have love for your people and want to see 1, 2 or all of your children take black wives/husbands you have to understand the odds of it not happening are higher. If thats something you care about.
For Black people, I believe serious interracial relationships are easiest for Black women who submit, black people that hate black people and black people that are patriarachal. In all cases there is no chance of the parents power struggling over how to raise the child culturally and the odds of everyone getting what they want are high.
