I think it's rather a matter of being an unproductive line of discussion. One of the key points to take from this article is that throwing your toys out of the pram because you disagree with others' viewpoints is counter-productive at best and illiberal at worst.

I'm vehemently opposed to the kind of activism described here, but 'if you don't like it then fuck off' is exactly the wrong attitude and will not solve this problem.
