likewise, while i don't support mandating helmets while motorcycling or bicycling as i feel that is an infringement on personal liberty (and have been firm on my refusal to wear a helmet while bicycling for years), i would be adamantly opposed to any legal regime that allows for exceptions to the rule based on "religious beliefs".

they should abolish the helmet laws....

....but, if you're going to pass a helmet law, if you must, then it should apply equally to everybody, regardless of physical characteristics or personal beliefs.

...and, if you are insistent that the law is unjust when applied to one group of people due to their beliefs, then you should conclude that it is unjust to all groups of people, and abolish it altogether.
