I'm pretty much "to each their own" and talk to about anyone that doesn't come off like an azzhat.
Some people like sportbikes and some don't...no biggie to me. I like most all types of bikes and don't judge a person by what they ride. I usually judge them once they open their mouth and start talking or once they start doing stupid chit. If you don't like what I do or what I ride...well just gtfo of my way...later...
The bike doesn't make the person.
As far as the cops around here...well they pay attention to sportbikes but I haven't ever experienced a bias against them IF you ride like you have some sense. If you don't and then you get caught well it pays to act like you have some sense when you get pulled.
I don't stunt but I do exceed the speedlimits quite a bit.
