Weird, r/anarchocapitalism will ban anyone who is on the left, and r/conservative will ban conservatives who speak out against Trump. Even r/TheMotte will ban people for things like tone. I've yet to find these mythical spaces where conservatives tolerate speech they in particular don't like.
The chans are the exception, and not the rule. Most normal human beings don't use any of the chans, but there are tens of tens of millions of subscribers to the online conservative spaces on Reddit and Facebook, and they're all ban happy.
