OTOH, we're seriously race (heh) mixed in NW Florida
Maybe you're so used to it, you don't notice. Or maybe it's said in other ways, eg, "Certain races do this thing or think that way." Or maybe it's more subtle, "That's just their culture." "That's just how their people are."
It's also maddening when discussing medical issues. "Why does my race have to be brought into it?” "Because certain ethnicities have problems with this particular medical condition moreso than others." "Because I'm more susceptible to x and I can't do y with you."
