It is their race - why not? They wanted it in there probably for geo-political reasons - the bikers voluntarily race - want more? This is the same as wanting to ban auto racing around corners because there are crashes there - lets ban hills that kids take skate boards down -- OH! I just thought of one you would love - let's ban KIDS! Then there would be no accidents. Yes, this is the 'nanny state' mentality. A nanny state mentality would be me calling for an American boycott or the force of law to ensure no pave sections ever appear in the TDF again. I'm merely stating I don't think it should be in. Period.
This is a pretty simple distinction. I'm not sure why it's lost on you.
