I disagree. I think the definition of hate and extremism has been warped to encompass things that aren't either of those things. And that's part of the problem. The rhetoric has become so hyperbolic that we're having a hard time coexisting.
The answer is for us to walk that back, and encourage actual dialogue, not run into our own safe bunkers.
You can talk to the people at your table in a restaurant, and it doesn't matter if the table beside you is talking about something you disagree with. The food tastes the same.
