It's a sissy game. Transformation, corruption. All good things. Racist cuck shit tho? So when my girl brings home a black man, or a Hispanic Sancho then that makes us racists? That's kind of insane.
He is describing a very specific phenomenon. Interracial sex is not what is being described. Even in a polyamarous settings.
What is being described is a specific form of fetishization that I like to call 'Being weird as FUCK about black dudes'. A thing done mostly by white dudes. Other races don't really get the same treatment as bad.
It all comes down to presentation and writing whether a sissy game, or
ANY porn, is being weird as fuck about black dudes or not. I will say that sissy games are usually really bad about it, to the point where I can't even see a black male character in one of these and not get a little bit suspicious. They become Chekovs BBC and I'm waiting for them to be portrayed as gross 2d racial caricatures. Often, I do not have to wait long. I find racial fetishization gross. So at this point I tend to avoid porn featuring black men if I have any concern that it will happen. I almost feel bad about it, but then I'll stumble into gross shit and feel justified once more.
It's more than a little goofy to attempt to water his very valid concerns down in the way that you have. If you are simply perhaps INTO being weird as fuck about black dudes, well, that's FINE. But you can't blame people for not sharing your fetish, or reasonably get defensive over it. It's fine as long as it's either fiction, or everyone involved is consenting, obviously.
And it's not racist to bring home a non-white person to fuck you, or your wife, or both of you. Obviously. It only is if you treat them in a racist manner. You are not being personally attacked. Unless you
are, in which case, I would say that maybe you should stop.
