I've found that the effective altruist community (and other "neo-rationalist"-adjacent communities) can be very arrogant about ethical philosophy.
Namely, they don't critically engage with alternatives to their ethical theory.

The 80K podcast interviews professional philosophers all the time, for example:
https://80000hours.org/podcast/episodes/hilary-greaves-compa... https://80000hours.org/podcast/episodes/will-macaskill-paral... https://80000hours.org/podcast/episodes/david-chalmers-natur... https://80000hours.org/podcast/episodes/peter-singer-advocac...
Or, perhaps you mean that they engage with philosophy and philosophers, but they don't spread their engagement around in the field the right way?
I wonder if part of it is youth. I am now 35 and have a more nuanced point of view on things (at least I try). When I was 25, I wasn't as good at it, and I was especially less experienced at communicating about it.
