Well shoot, now here's another branch to go down! I think its safe to say that in many cases, religion and ethnicity (I'm still not convinced there's more than one race of humanity on the planet) go hand in hand, at least for the majority of people of a particular religion or ethnic group.
Regardless, bigotry is bigotry and unless your name is Archie Bunker, it has no place here. I think this particular dude is seeking media attention (have you seen the poses he assumes on his big hunk of chrome?) and the media and human rights groups are always hungry for a good story. I disagree with his position based on the fact that we have rules and laws in place governing the use of motor vehicles. Abide by the rules and you get to play ball.
We're passing laws all the time governing what you can and cannot do while operating a vehicle. You can't drink, you can't be asleep, you can't wear a blindfold, you have to wear a seatbelt, in some places you can't talk on the phone, you can't play guitar, soon you won't be able to smoke if your kids are with you (like we should need a law for that?) etc. etc. etc.
And you've got to wear a helmet when you ride a motorcycle. End of discussion.
So long as we have taxpayer supported healthcare, and no tax-base to extract funds from people who knowingly put themselves at higher risk of health problems (like taxes on cigarettes, booze etc.) then you'd better wear that fucking helmet or I'm coming to the hospital to pull the plug on you when you're on life support at my expense.
