I go into left-wing and right-wing pages and argue with people. I like to argue, so sue me. I argue abortion with righties all the time (including directly with Ben Carson himself on his page once)...they go unhinged usually for a short amount of time but I've never been banned. I argue climate change with lefties...instaban.
In the case of Occupy Democrats, as soon as I started posting rather benign comments arguing their suggested primary strategy, someone from a California IP address hacked into my account to poke around, I'm guessing to collect dirt, and I was banned from posting further.
I post things about ideas I support on the left, some of my more conservative friends will argue, no big deal. When I post things about ideas I support on the right, friends disappear off my friends list.
The people running the show behind the scenes on the left, not always, but tend to be less tolerant of conservatives than the other way around.
Bayviking: There is plenty of fake news/egregious bias on both sides. I'm fairly moderate and I track both sides and there's some straight up -------- floating around. I'd cite a specific example, but I'm probably already inviting a slew of personal attacks just by mentioning I had an argument about climate change.
Fox News lemmings and MSNBC lemmings are the same thing.
