I'm very confident there's at least one paid troll on DU, because it just makes sense from the RNC perspective. Probably more than that. From a conservative and Republican point of view, why not disrupt the largest Democratic Party-oriented (not endorsed or affiliated, of course) on the internet ?
Unpaid trolls, plenty of them. They love to argue (not discuss), be snarky, be disrespectful, get people hidden, and in extreme cases get people PPR'ed. From what I've seen, they are 100% white (or that's what they claim). It was interesting who did not rec my giant thread about welcoming black people back to DU and who did not comment. It's interesting who NEVER recs or positively comments in racism-related threads. It's interesting who never starts a positive racism-related thread. One can judge for oneself from all pieces of evidence.
I'm a white guy also. I also believe in listening and learning. I'm still learning about cultural appropriation versus cultural assimilation, so I'm not commenting on those threads. What I do know is, we white people need to be respectful and listen. We always need to be respectful. You're a good guy, Tobin, and I'm glad you're here. Some of the other white people, imho, need to leave DU. If one cannot respect black people, one needs to leave DU and leave the Democratic Party. It's just that simple.
