Effective altruism is based on the core belief that all people count equally. We unequivocally condemn Nick Bostrom’s recklessly flawed and reprehensible words. We reject this unacceptable racist language, and the callous discussion of ideas that can and have harmed Black people. It is fundamentally inconsistent with our mission of building an inclusive and welcoming community.

This looks like retconning of history. EA and rationalism go way back, and the entire premise of EA is that determining what makes more good through "rationalist", or more precisely, consequentialist lens is moral. There is no conflict of principles.
The quality of discussion on the value of tolerating Bostrom's (or anyone else's ) opinions on race&IQ is incredibly low, and the discussion is informed by emotion rather than even trivial consequentialist analysis. The failure to approach this issue analytically is a failure both by Rationalist and by old-school EA standards.
