I don't think we can, and even if we did, the media/BLM/government would find this thread and the whole thing would backfire.
>Considering the hatred they have for whites due to slavery, how about we get them to go after Islam? Just meme them with middle eastern slave facts.
They hate whites because of constant media indoctrination, they would probably see picture attached as "islamophobic" and the media would pump out claims that it was "the far-right trying to subvert a movement" they've already made the agent provocateur claims.
If you do this then your going right into the hands of the media.
It would be much better just to redpill them and make them leave BLM.
TL;DR this probably won't work, there is literally much better things you could do.
