I agree -- I think that right wing economics falls apart under debate and scrutiny (ie, it reveals itself to be based on the interests of the wealthy and powerful and to the disadvantage of the poor and middle class) and discussion is a good thing. But I haven't seen many economists becoming subject to deplatforming in the way that racist or misogynistic speakers like Ann Coulter, Milo Yiannopoulos, Richard Spencer, etc have (rightfully) been, so I don't see this as really an issue.
