Reddit thinks they're trying to be non-racist by doing this. The actual result is they are exacerbating the problem by doing this.
If you kick these people out of these subs, they're not automatically not going to be racist. They're going to find another place to be racist. A place where it's even more dangerous and even less moderated. Like where do they think these racists go? This out of sight out of mind shit is dangerous. That's why Trump won in the first place, because media ignored literally all of the middle of America.
So yeah reddit thinks they are creating a better world. No, reddit is contributing to the political divide.
