Doesn't it put more strain on the clutch?
If you've got a reasonable engine (and even if you don't sometimes, but it'll be more work) then the clutch will be designed to take far more punishment than gently pulling away in second

To pull away without labouring the engine in second gear in mine doesn't need revs of much more than 1000/min and I doubt the clutch even notices..
Pulling away more rapidly, obviously 1st gear is the tool for the job, but 2nd gear is plenty fast enough for typical stop/start driving, not that I pull away in 2nd often anyway.
