Yeah, I know, it was a joke - I thought the smiley thing gave it away.. Oh well.. I'll try again later..Sorry bro, but that's the WORST logic I've ever seen.
Kill switches and (especially) frame sliders are made for emergency type situations. Actually, the kill switch can be used to turn the bike off when you park it too (that's what the MSF teaches anyway) and I use it for just that purpose.
The clutch was not designed to be an emergency use only device. Your transmission was designed to be shifted using a clutch in NORMAL operations. Is it necessary to shift the bike using the clutch? No, but you could also ride your bike around and brake using only engine braking and the bottom of your shoes instead of the brakes.
