Actually, it's perfectly logical that people might come to such a conclusion when their reference of most bikers with tattoos happen to have criminal tendencies. It may not be correct, but that doesn't make it illogical. And just because someones references lead them to a certain conclusion... that doesn't necessarily make them narrow minded.Oh yes it does, I'll give you an example. One of my older brothers has tattoo's on his back and his arms and he's also a biker. He's probably the kindest and most helpfull person you could ever meet yet people who don't know him always asssume he must be a bit of a criminal involved in shady stuff and some people are even afraid of him. They make that conclusion based solely on his appearence without even knowing him. That's neither logical or open minded.
