There are alot more of these people out there. Instead of joining these groups, they will be sympathetic to their cause. They will use code words that other members will recognize.
There are even black people like Roland Martin or Boyce Watkins who support them behind the scenes for financial gain. They will do a story like this and than drop code words in another video offering them support. Damn just handing you over to your white slaver for money.
XXXTentacion was doing the same thing, giving a shout out to Dylan Roof
