I don’t think anyone’s gonna die soon. What we are a couple steps away from, I think, is an environment where this rebuttal would be considered hate speech and the signatories would be fired for endorsing it. (We might be only half a step away, honestly; I give it a 50% chance that one of the signatories faces a Title IX complaint about it by next week, although I understand that such an unconfident prediction doesn’t really mean much.)
