These don’t sound like Texans to me. They also don’t sound like any of the Bikers we know. Around here, in Tennessee, Bikers do benefits and rides to help our vets, pay medical costs for sick kids, families who have lost their homes to fires, all kinds of good work. I haven’t heard of this kind of trash since the late sixties and early seventies, and even then, it wasn’t that prevalent.
The level of violence seems odd to me. I have not heard of biker gang wars in rural Virginia since around the 80’s. Most of the gangs were infiltrated and broken up. But these gang members did not go on rampages like the one described in the news. A fight starting in a restroom would not turn into a free for all.
These are the “1%” of bikers who are gang members. Do an image search of motorcycle gangs to see the “1%” patch on their jackets.
