When it comes to the website Tumblr Sexypedia which focuses on characters considered sexy by Tumblr nerd standards where it boils down to the characters’ angst, malevolence, power, style, intelligence and being pale or ethnically white. There’s only one live action character of colour out of all the anime characters enlisted there (Hisoka Morow could probably be a white man), since that website enlists being ethnically white as what makes the character Tumblr sexy it does point out to a manic pixie dream girl quality that’s not bequeathed to blacks.
In the sense that blacks are only attractive if they fit stereotypes, as what the vlogger Kai Decadence pointed out in Reddit. Black men are only attractive if they are manly, sexually top their partners, promiscuous, thuggish, urban and have large penises (which’s something not all black men have, likewise there are black men who’re celibate, effeminate* or are in a monogamous relationship). Manic pixie dream girls are attractive for being quirky and unusual, but that’s usually bequeathed to white characters (when it comes to Asian women having the hair streak, it’s like a bad attempt at subverting stereotypes about Asian women).
A white person can live outside of stereotypes and be quirky, black people only live as stereotypes. There are black men with a lot of angst, style, power and malevolence but they don’t have the same manic pixie dream girl status their white counterparts are given. (I also think this goes hand in hand with being unable to empathise with black people, which dehumanises them along with the stereotyping of being superhuman, promiscuous and well-endowed, which’s something not all black people are.)
Black women don’t get to be manic pixie dream girls as they’re stereotyped as either sexless mammies, oversexed Jezebels, domineering Sapphires or animals. They don’t get to be quirky the way some of them are in real life, it feels like with black men black women are only attractive if they fit a stereotype in addition to fitting white beauty standards. That still proves my point that when it comes to manic pixie dream girls and Tumblr sexymen (the latter’s evidently a male version of the former), black people don’t get to be either of them.
Again, it’s got to do with stereotypes they’re expected to fulfill so while some white characters get rejected for being too conventionally attractive (which again fuels my suspicion that Tumblr sexymen are essentially manic pixie dream girls), black characters never get mentioned since the only way they’d ever be attractive is if they fulfill a stereotype (Finn gets slotted into that well-endowed stereotype but his actor might be average or less than that).
There are probably scores of angsty, malevolent, intelligent or powerful black characters whether in Western media or in African ones, the latter because they’d be too obscure and the former for some reason those characters never get included as Tumblr sexymen. That’s probably true for Latino characters and Asian characters outside of Japanese media, where if the latter does show up they’d be stereotyped as sexless even if there are Asian men who do have sex with white women (most notably Balinese gigolos).
Latino characters are only sexy if they fulfill stereotypes, which’s why (brown) Latino characters like Jaime Reyes never get included as Tumblr sexymen. Rick Sanchez might technically be Latino or Hispanic and yes white people can be Latino too but since he’s white, he gets a pass and probably so does Professor Membrane. That still proves my point that black and brown characters don’t get to be Tumblr sexymen, only as stereotypes but not quirky Tumblr hunks.
