Another professor bites the dust

I'm not through it all yet, but it would seem a safe space would be more like an "epistemic bubble" by those definitions.

I don't really think so. A safe space isn't really an epistemic space, nor is it one from which relevant voices are excluded by omission (rather: hostile voices are excluded by design--but, again, it's not really an epistemological thing).

The definition creep of what counts as "hostile" is the big problem; for instance, among the "healthy-at-any-size" crowd, just talking about things like fitness is seen as "hostile", despite all of the relevant medical evidence about what conditions optimize health.
