given the fact that you claim to study sociology, it is shocking how misinformed you are and that you use an example of ONE tv show to substantiate your claim.
First of all you fail to give any valid sources or evidence for your statements. You making a poll does not count as one, as it cant be considered representative. I have made tons of polls at uni but that doesnt mean they represent the truth.
NO ONE debated that there are more white girls who like/date black guys than white men who like/date black women. The issue people have with your comment is that you state MOST white women prefer black men over white men. This is not true. In fact, in each race category the majority prefer to date/marry inside their own race, be it Asian, White, Black. In the UK the percentage of interracial marriages is still very low:
http://www.mixedmediawatch.com/2005/03/22/new-report-on-interracial-marriage-in-uk/In the USA you will find less white girls dating/marrying black guys, the same applies to other countries which i will disregard here because they usually have a much smaller black minority than the US/UK.
Now i can give you a tv show example as well. The very popular show " The Bachelor" which is in its 14th season or so never had a black bachelor (neither had its female counterpart " the bachelorette"). The reason for this is that the core audience are white women and producers know that the majority of these are not attracted to black men. Also, no Bachelor/Bachelorette ever picked a black person as their love interest.
Also, you are wrong if you think white women are more open to interracial dating than men. In the US more white men have interracial marriages but with asian women, not black women.
Have you also considered that these white women who date black men dont necessarily have to think that they are more attractive than white men in general? They might just not care what race their partner is or find them equally attractive.
You seem very desperate to try to make everyone think white women are flocking to black men and are drooling over them. That is more wishful thinking on your part and no way you are white, you are black and have an inferiority complex which is sad. Interracial dating/marriages is still not as common which is unfortunate. I would love for it to become more common because i believe it is a great way for society to become more open-minded. But twisting the facts does nothing to pave the way for this.
You mentioned how this girl Bella can not speak for all white women, well neither can you speak for all black people or white women. You wont get a more accurate statistic than the link i provided, so you should just rest your case now, it is getting pathetic.
About porn, yes there are sexual stereotypes about black men, same as about latino lovers. But only an idiot would buy into stereotypes in the first place.
