If you had followed the thread, you'd know that I didn't bring up Dylan Roof. I was replying to someone else who did. Someone who was trying to suggest that all the mass killings committed by lone white guys are always Republican. This is obviously false to any informed person with a thinking brain.
I brought up George Soros because he funds violent left-wing bigoted groups. And again, why did you bring up white supremacists?  Most Republicans strongly denounce them, and I haven't heard of any right-wing billionaires funding their cause like George Soros funds the left-wing violent bigots.
