After seeing r/asianboyswhitecocks banned and r/asianfemboys banned and r/asiansissification banned and r/whitemenonasianboys/ banned -- which are subreddits mostly catering to Whites (over all other races) dominating Asians -- I looked into it a bit more, as most of my experiences observing reddit is they operate much like Twitter, with SJW-type politics; for example, in Twitters case, where only racism towards whites or right wingers seems to be tolerated.

However, on reddit, until now it seems to have been tolerated if it were in the realms of sex-fetish; perhaps not so much any more.

In any case, I couldn't help but also notice that these sex-fetish subreddits are also banned now:

/r/whitemenruletheworld/

/r/WhiteWorldDomination/

/r/bwcsissies

Of course, these sex-fetish subreddits are still alive and well:

/r/BlackWorldOrder/

r/WhiteboyExtinction/ (I'd be curious how long a r/BlackBoyExtinction would last)

r/BlackIsBetter/

r/BBCsissies

While it could be coincidence and there were modding problems with all of these white dominant subreddits and not for their black counterparts, it seems unlikely to this extent.
