I am really surprised at the reaction on HN. So what's the state of things, open racism is fine so long as you are a really smart programmer? Please educate me on what I am missing here, it seems everyone is in agreement that this person is racist and hosted repos reflecting their views and not just HN but Github are ok with this. I am honestly asking here, my understanding has to be wrong right? If so what am I missing? My earlier comments praising GH were downvoted even though I included a link to the whitesonly rimworld mod repo. Has the makeup of the HN community changed that much?
