> Idk, I feel like saying that humans should somehow manage to turn off grouping and categorizing things is kind of lazy.

I don't think that's what danieltillett was calling for at all. Rather, I think he was arguing for not letting group-level categorisations - such as gender or race - totally dominate over and blind us to attributes of individuals that may differ from what we would expect from our preconceived stereotypes of groups. Because when we do that with race, we do recognise that as racist - maybe not when the race in question is white, but in other cases, yes.
