I'm not sure Eliezer qualifies as an "overly sensitive member of a minority group" but I take your point. I think he's making a pragmatic decision but we can disagree.

In this particular case, I think Eliezer is arguing that the hypothetical woman who thinks all evolutionary psychology discussions are sexist is not a rationalist. As such she has no rationalist honor and would probably not respond as you (being a male rationalist) would. I think it's fair to give her (as a female assumed-non-rationalist) a little breathing room, which is what I think Eliezer is suggesting.

I think this is consistent with his narrative of trying to recruit/grow the rationalist pool, and as such trying to be more tolerant/welcoming of people who may not yet be rationalists but are interested and learning.
