Make your own choice, and it is does not have to be deeply informed as long as you have the basic grasp of what it is, what its for and its limitations.
As with all things, I believe that if this (think seat belts as a comparison) or anything else for that matter was proved to be of real benefit (pros) and that benefit outweighs and drawbacks (cons) then I would not appeal against compulsion.
I think this is a lot different to promoting it and therefore it is not an 'agenda' as such. I just dont have an issue with experts (presuming these would be the ones making this decision) in making our lives safer.
For now people can chose to wear or not it makes no difference to my life. But when people tell me I must be informed before I can chose to wear a helmet or they want to make me feel like I'm contributing to poor health by wearing one (the obesity argument) then I feel I am justified in challenging this. This is often wrongly presumed to be pro compulsion which it clearly isn't
.
All above is my opinion. (not to be confused intentionally or not with promoting of facts, studies, evidence or advice)
