I think it's fairly straight forward. Professor Curry expressed controversial views (which, personally, I think are wrong). An alleged journalist then spins them to make them appear worse than they are and the Professor starts getting death threats etc.
So, genuine question, no snark intended: what is it that you are unsure about?
First of all, that if I believe in free speech as far ad I do, then Dreher's views are just as allowed as Curry's. I'm not sure why you want to colour that by referring to alleged journalist and spin. Secondly, I don't think that Dreher is responsible for the death threats and we need to be careful that we are not then looking to censor people because others are lunatics. There's ni incitement that I can see in Dreher's position.
Thirdly, and this is where I am most ambivalent, if the views of Curry can be equated to Stephens which the university tried to get banned then that seems odd. The interplay between Curry's own freedom of speech, and the university as an institution's freedom to not approve of personal views seems to me to mean that it's not their duty to defend the statement in the way Curry seems to have wanted.
In the end, what I am unsure about is whether in any way this was avoidable. It looks inevitable and yet is obviously not an ideal conclusion.
