Maybe take some time to find out why people feel strongly.
Because they feel that one day AUK will decide that helemts are now compulsory... To be honest, an association with 6,000 members which promotes organised events with 50-100 participants (with one exception) is almost invisible and has zero mediatic power... so if one day helmets will become compulsory by law, it will not be because of AUK pushing for it.
On the other hand, if helmets will become law, then there is nothing AUK can do to stop that happening... so you can all chill out, do as you think it's best, follow the law whatever that is and stop getting agitated about some otherwordly realities that might or might never happen and more importantly you can't do anything about.
Equally, I don't see the point of someone waving his hands to persuade AUK to pursue a helmet only coverage... the law is clear and the law does not impose helmets... end of the aggro
