The problem is "honest disagreement and talking" isn't. One person's honest disagreement is inciting violence, and with coded signals and dogwhistles, it's not a subject that everyone will agree on. Things that are clearly on one side or there other of the line aren't in question. It's more subtle stuff that can be argued either way, eg "When the looting starts, the shooting starts", where it gets more contentious.

Pretending it's all just honest disagreement is being naive.
