I totally understand. But the media plays a big part as to how society plays. Everyone watches television, reads magazines, watches movies etc. Young and old. All races. 
Twerking has been around since the 80s. Due to Miley Cyrus' controversial Video Music Awards performance, it has resurrected into popularity. All because of this videos on youtube of people twerking proclaiming that it's a new fad and craze makes me sick. 
Scandal is a very popular television series right now. It is one of the first to showcase a black female in a lead role having an interracial relationship. Black women and white men relationships are still frowned upon in this society, especially in America. Unlike black men and white women relationships. Black women are more willing to date men of other races, not limited to white because of that.
DTLA just wasn't good enough to hold your argument. 
The only good show which could win your argument would be Modern Family which is one of the highest rated shows on television which feature both white partners, and no black characters period. 
And I used to disagree with this statement as before I thought it was gay black men who were refusing to date white men, but due to the fact that I've talked to other gay black men and men of color in general who were associates of mine, not to mention I've tried online dating, networking, parties, meeting people at work, and I've come to the fact that white men might flirt and have fantasies of the big black dick syndrome, but in reality when it comes to interracial they are interested in black men the least, and asian men are at the top of the totem pole with probably any other race in between or below black men in rare cases.
And I'm only speaking of my experiences and friends experiences, as the same issues could happen to straight interracial couples, but the majority of the white men that I've been with and I've felt were going to be my soul mate, never wanted to go on dates. It was always late night adventures at his house, he wouldn't allow me to text him at certain times, he did heavy drug and alcohol abuse, I wasn't allowed at his house, his family had beef with me, sex was too kinky (not that I have a problem with it, but some of the things were a little extreme), I couldn't take pictures of him, etc. Just some common stereotypes that really aren't ever discussed but happen always. Mainly because interracial relationships for the most part are still taboo in the United States, straight or gay.
I totally agree to some parts of what you said, but just understand that entertainment plays a big part of it.
Plus it's four minorities being jumbled together. 
1.Gay
2.Gay person of color.
3.Interracial couple
4.Gay Interracial couple.
