I carry when I ride....so unless I relish the idea of prison walls and sex with an inmate named "Tiny" I just ride away...no gestures, no punching, no telling anyone off. Anything to the contrary and I'm the aggressor and that's bad for me and bad for the moron involved. Keeps you honest, but I carry because someday it might meet someone who will kill me over a stupid traffic incident, or the stuff in my wallet.
