"We at Vox do not take institutional positions on most questions, and we encourage our writers to debate and disagree. But direct encouragement of riots crosses a line between expressing a contrary opinion and directly encouraging dangerous, illegal activity...."
Vox has "suspended" Rensin.
I had to go elsewhere to find the text of the over-the-line tweets. Here, at Mediaite: "Advice: If Trump comes to your town, start a riot." "Listen, if Trump is Hitler then you've got no business condemning rioters. If he isn't, you've got no business pretending normal is better." "Let's be clear: It's never a shame to storm the barricades set up around a fascist."
Here's Rensin's Twitter feed. Those posts that got him suspended are still up, and there's a lot more since then, such as: "You spent a year saying Trump was a fascist, and particularly an anti-Hispanic bigot. Hispanics take that seriously, and you're Shocked." "If you too believe he's a fascist, then ask yourself what it means to concern troll poor, Latino folks who take that belief seriously." "It remains unclear to me what people believe the appropriate response to fascism is. Say 'fascist, fascist, fascist', people will freak." "If Trump *isn't* a fascist or an existential threat to democracy, fine. But then let's stop saying that he is."
