Race play is a brand of kink, just like any other. It's a form of transgression. My work, often focuses on breaking down psychological taboos. I film incest role play, but I do not condone incest. I do "forced penectomy" medical role play, but I do not support forcible surgery on anyone. I perform role plays in which the viewer is "forced" into a permanent infantile stale with drugs and surgery, and yet I find the idea horrific if brought into reality. I've created "knockout" porn, and I vehemently oppose any form of non-consensual sexual contact. In my catalog, I have role play videos in which I call the viewer homophobic slurs and excoriate his very manhood, yet I am queer myself, as are my primary partners. I could go on and on.
I understand that many people will find my most transgressive scenarios upsetting, despite the fact that they are entirely fictional. If the material bothers you, then you're not the intended audience. I suggest you don't watch it.
Your questions, my answers:
There is a substantial audience that likes derogatory language during sexual situations. Racist, homophobic, sexist, etc. words find their way into porn all the time for one reason: someone in the audience is paying to hear them. Actors should find their own comfort zone with slurs and demeaning language. To me, it's the same as calling a woman a "filthy disgusting cumbucket whore." A select audience likes it. Many people find it deplorable, even as a fantasy. And it's certainly not something to do in day to day life. However, within the boundaries of a sexual scene, if all parties are consenting and desirous of such action, it's perfectly fine to do. When someone chooses to watch my video, no matter who they are, no matter their reasons, that is their consent to participate.
Actresses are free to work with whom they choose. It's not my place govern other people's behavior. As for myself, I don't give a damn about my partner's race. I mostly care about how polite and professional they are.
You're absolutely correct. The industry is racist towards ALL races other than white. Companies vary in how much they play it up or down, and it's a sad fact. Think of this: how many Asian men do you see in mainstream American porn? Exactly. It can be a damn sexist and ableist scene, too. Society looks downright ugly in the mirror with all her makeup off, huh?
I'm sure my fanbase contains conservative anti-porn Christians, married men who have "sworn off" porn, gun enthusiasts, oxycontin addicts, yoga teachers, high powered executives with a clean cut image, elementary school principals, military personnel, doctors, clergy, stay at home moms, undiagnosed sociopaths, antivaxxers, and white supremacists, to name a few. Their lives are their own. My role in their stories is minuscule. You'd do better to talk to white supremacists if that's a movement you want to stamp out. My work is not going to convert someone to a certain mentality any more than you can "catch the gay" by looking at homosexual porn.
Fantasy is not reality. Fantasy is not reality. FANTASY IS NOT REALITY. My work is an act of fiction. The money is "worth it" because other than upsetting people for whom it is not intended (and delighting those for whom it is intended), my work's effect on the culture is nil. The majority of people can tell the difference between a porn video role play and reality. (Spoiler alert for pizza delivery dudes: the hot milf is NOT going to pay for her pizza by blowing you.)
I'm going to go make some weird smut with my bi-racial queer partner now.
