We can start with plainspoken intolerance, because it is pretty easy to identify. Going beyond that would be difficult, perhaps too difficult, but I don't think we need to go that far.
We may be talking about different things, then. Would you be willing to give an example of acceptable intolerance? FWIW, in my mind, when I say 'intolerance' I am specifically not including legitimate policy disagreements or opinions about behavior.
