This article is based on the assumption that those two statements from Rockford were the actual reason for his disinvitation - because that's "everything [the author's] been able to find". Which is not the case according to nodevember's statement[1].
Besides, the fact that the author is criticising people for calling for a disinvite of a white supremacist speaker from LamdaConf[2] doesn't quite increase my trust in his opinions.
