Its most likely the same reason uneducated people like your self start threads like this. I like big body cars and im white. Impalas, Crown Vics, the Merc version, Caprices, Lincolns, Caddys. They are nice looking cars. I dont think they need 28" that look like a grill but its whatever. The thing is, they need to 1 up someone. Same reason most of you try to out bump someone at a stop light, floor it when someone gets next to you on the highway or anything else. People see it, they like it, so they try to one up it. I like lifted trucks too, i dont like people who lift them just to lift it though. I think a vehicle should be purpose built, if i have a truck that is going off-road or i get snow a lot, my shit will be lifted. If i drive on the highway, ill lower a 2 wheel drive.
Regardless, i think you would look less ignorant if you stopped making random generalizations and stereo types about people because in one way or another, you can be stereo typed the same way.
