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.

That paragraph does feel kind of confused to me, though it's hard to be precise in lists of principles like this.
As jimrandomh says above, it is widely accepted in EA that time and location do not matter morally (well, moreso location, I think it's actually pretty common for EAs to think that far future lives are worth less than present lives, though I don't agree with this reasoning). But that clearly does not imply that all people count equally, given that there are many possible reasons for differing moral weights.
