No, you're right. It's just the textbook use of stigma to try and enforce normalcy in a group. They get the bad rap because they aren't part of the Hell's Angel starter kit a lot of cruiser riders in the US choose. Cruiser riders try to enforce the 70's biker uniform on everyone. Most of the time with great effect, to be fair. I mean, every rally I've attended in the last ... 20 or so years, has been a sea of black vests, do rags, black chaps, fringe, conchos, and now those stupid getback whips. How a guy in black chaps and a black leather vest can demean a bag as unmanly is beyond me.
