I'll happily pay a registration fee and insurance but it still won't stop people for trying to run me over just because I'm on my bike. Also, homeowners insurance would cover and BI/PD I might cause you. And, I have 4 vehicles so I pay plenty of taxes for your roads.
The absolute dumbest argument ever made. If I had a tag on my bike you'd still hate me so who cares. Also, my 15 lb bike isn't damaging the roads that tags help pay for.
