This is the problem with black and white statements, there's always someone ready to jump in and prove there's middle ground. I am a well off white male and I've ridden a beaten up old dirt bike in the street plenty of times. Why? Because I like to ride off road, but you don't get to do that without tune ups, repairs etc. During riding season I am sure I annoyed neighbors with a weekly ten minute ride around a few blocks (and a large abandoned lot in my old city neighborhood). I even skip the helmet often during this so I can hear sounds as I diagnose a problem.
