Different races

I keep telling my kids that there’s not different races cause all we hear about these days is race this and race that . “There’s only ONE race you guys; the human race. We’re literally all cousins and we all come from Adam and Eve. “ Of course my 13 year old who loves to argue with me has to come up with something slick just so he can oppose me cause he’s got my dna... Cooper says “you’re wrong, you keep saying there’s not different races but there’s tons of different races. We have 5k’s, 10k’s, there’s boat races, horse races, we’ve got all kind of races.” Can’t even tell him he’s wrong,
