No, no, they're not pro-slavery, just pro-slavery for whites. Wow this guy is a giant pantload of disinformation. Especially the part where the antiFreeSpeech folks only show up masked, wearing all black and carrying weapons for "self protection".
You have violent mobs (antifa) attacking peaceful demonstrators. The police, nor the local government does anything to stop it. That’s when the militias come in. They’re keeping the peace when corrupt govt finds it politically convenient to stoke violence. That’s what they’re supposed to do morons. If you leftwing assholes don’t want militias involved, then order the police to do their jobs. NPR is an echo chamber for leftists.
