The narrow view is the intention I think. They want to “allow right wing views” as long as they are the milk toast “well we just disagree about how much money the government should get, the acceptable options are A LOT and MORE”. When it really gets into it, totally reasonable positions that one side just doesn’t want to hear suddenly become “racist” or “extreme”.

And to the latter part - no. No one ever thinks their views will be the wrong ones. This lack of foresight seems to be a recent thing in my opinion.
