Why all women prefer white guys and avoid black guys?

I see black guys on TV with white and Asian women worshiping black guys and even being the racial preference above the white guys, but in real life I only see black guys with black girls, and white guys with Asian girls, white girls, Latinas, every kind of woman.

Black boys are so ugly and bad to be the least desired by women?

At least we are the third race getting white women, but this is too little, I watch much more black men getting white and Asian women in the media and films musics but whites are the preference of Asian women and getting more them. WHY?

How can you have so many White guys with Asian girls with Fewer Asian people compared to blacks people?

At least we are the third race who white women are marrying, after latinos.

But it's so little compared to what I watch in TV series, movies and music.

Why Asian girls are going for white guys instead of blacks? Why do you hate blacks so much to go for whites?
