Keep in mind that every single nasty loud leftist activist you see online eagerly supports the exact same kind of genocide happening to white people in the US. The worst ones will gleefully tell you this to your face, but the slightly smarter/less impulsive ones who lie about it genuinely want you and your family dead too.
Unlike the way leftists behave (constant hysterical lies and emotional terrorism to batter you into doing what they want), there's no reason a normal person would make up a story about Haitians butchering their cat and post it on Facebook. There's also no reason to argue with deboonkers beyond "fuck you" and slurs until they give up because they won't accept the idea that ice is cold from someone they've identified as an enemy.
These are the people who genuinely think cops should just shoot guns out of people's hand when they're in a standoff and correcting them only makes them get really aggressive and nasty.
