I wonder this as well. I think it's tied into a lack of nuance that has arisen as a result of the polarization of viewpoints in the last decade or so. The intention is good, I think. Basically, what we're saying is obviously correct and what they're saying is obviously incorrect, maybe we should stop them from saying obviously incorrect things. The problem with that is that the world isn't so black and white. You need to hear all sides if you want to look at things critically. Doing that will also help one group to at least understand where another group is coming from, or at the very least what prompted them to adopt some seemingly indefensible ideas. You can't get there, though, if you don't allow their ideas to be heard and debated. That will keep the door open for both sides to be able to talk to each other. I have no ideas at all on how to make that actually happen, though. I say this as someone who doesn't identify strongly with either of the major "sides" in the current U.S. political climate.
