She's right, and not just about r/T_D but in so many other subreddits, -- some stood up for the singular purpose of being racist, and some that are just racist on top of whatever other thing they represent -- and the uncomfortable truth is that to some degree any profitable online community/social network is forced to at minimum tolerate casual racism. To stamp it out is too tall a task for any social media platform of any significant mass... including Twitter, Facebook, Instagram, WhatsApp, and so on. It's also worth mentioning, at least, the conspiracy theory that Reddit is proactively censoring sinophobic speech on it's platform. But, I don't know if that's been proven for certain.
