I don't think your comparison is valid at all, you seem to see cycling as a sport whereas many of us see it simply as a mode of transport with no competitive element whatsoever.
Nope, I see them both as physical activities that mean different things to different people at different times
Sometimes my bike is just the best way to go and pick up the sunday papers, other times its is full on work-out.
Some people ( often in European resorts more than N.America admittedly) simply view skiing as a convenient way to get from one bar to another.
Another thing is for sure, very few skiers and even less snowboarder view what they are doing as competitive.
My observation was centred on the different attitude (and strength of feeling) between the cycling community and the snow sports community, which I thought was interesting
Exactly, you'd need to compare cycling with something like cross country skiing to get a more reasonable comparison. In the same way that the different forms of cycling can be viewed, I would wear a cycle helmet for MTBing but not for commuting, going to the shops, social riding, etc. I suspect I'd wear a helmet for snowboarding but that I'm also unlikely ever to snowboard to work or the shops.
I doubt you have any experience of the average person cross country skiing then - they are, in the most part, incredible slow.
My other observation is that the constant niggling, some times self righteous lecturing of the pro-helmet crowd is exactly the wrong approach to achieve the outcome they want. I can't see any strong-willed individual who does not want to wear a helmet changing their mind because some-one made a 'knock-out' comment on an internet forum. Most parents will know the direct approach is a disaster with kids .... the best tactic is to ask them to do the opposite.
So if you really don't want to start wearing a helmet be very suspicious of people who suggest you shouldn't
Off now to do 20 miles, have a good day everyone.
PS For those of you who think that helmet wearing is a marketing ploy by the brands, you are giving them way more credit than they deserve - My Missus worked at senior level in the sports brand world for a while, I can assure you that the level of marketing sophistication definitely lacks that level of strategy. Pretty much all of the big companies are now listed - so the only focus is sell more in the next quarter. Sad but true. If you want to ruin a good brand then take it public or let the VC crowd get there hands on it. Remember just my personal opinion. Others have the right to dis-agree
