There are plenty of people who drive pickups because they like them, not because they fulfil a utilitarian purpose, and not all of them are assholes.

I would say the issue is more that there has been little to no progress in mainstream consumer car aesthetics in the past 25 years. It used to be that you could clearly tell a 50s car from a 60s car from a 70s car from an 80s car, etc. Everything from the past 25 years or so is pretty indistinguishable, so something comes along with a clear but possibly misguided aesthetic vision, its naturally going to appeal to some people.
