No defensiveness involved - at least not on my side. Not so sure about yours. It's just different, and different techniques involved.
What is annoying is people trying to push track techniques where they're inappropriate for the job in hand. I have the same objection to street riders trying to push track riders into using techniques that are inappropriate for the track, but you don't see much of that.
It is worth remembering that tables of stopping distances are not much use on the track - you don't usually stop - and you need to keep the bike balanced enough that after braking you can get the power back on. Don't know about you, but I don't usually drop into a curve with the rear wheel still in the air. It doesn't accelerate at all well like that lol.
