Here's Alonso on his FB page cross country sking with out a helmet as well. 
And yes Sagi it does depend on the event... so why would a news outlet write a red meat article about it and then share it with the red meat eaters? 
First of all, I think the problem fans are having with Hamilton's pictures is the timing!
As far as I'm concerned, he's a big boy and he can decide for himself what he does or
doesn't wear when he skis, snowboards, or anything else. Nor do I care what he does
or doesn't post about.
Secondly, you needn't get defensive, as I hardly posted a condemnation of Hamilton!!
Finding pictures of Olympians and Alonso not wearing helmets is basically suggesting
that if other people are doing it, then it's ok that he do it, too. Again, I think the
problem seems to be in the timing.
As for the "red meat" comment, if you're referring to me, then please understand that
my intention was to share something I found odd. Again, it wasn't a condemnation.
