It looks like some other academics have responded to the letter condemning Stock, with a letter of their own supporting her. They don't say they agree with her, just that she should be allowed to speak even if it offends others.
In particular I liked this:
"It cannot become our standard that where analysis and discussion of matters of public concern may cause offense, the social and institutional consequences of engagement are so costly that few will be willing to do the work. It cannot become our standard that the mere allegation of harm caused by some writing or speech, in the absence of any specific evidence to that effect, is sufficient to trigger such consequences."
