I notice you choose to shift the goalpost instead of engaging with the central point. The central point, stated clearly and unequivocally, is that the project maintainer wrote he welcomes anybody and does not care about race, and you call this racist, and thus there is a huge contradiction.
I suspect you double down because you are so captured by your emotions that you cannot possibly admit the lapse in critical thinking. I predict going that path won't take you far on HN.
A common refrain against any attempt to mitigate unjust effects of past racial injustice (affirmative action, protesting against unjust policing, DEI, etc) is that the mitigation itself is racist, and the best thing would be to treat everyone "equally" going forward. Thus the "all lives matter" and "we welcome everybody regardless of race" are the same coin.
I am perfectly fine.
