Actually. I disagree with your logic.
-People that claim it's bad for your car, aren't doing it right. I know people who no lift shift all the time and have had no problems what so ever with their transmission. If you don't know how to do it, then yes, you will damage your tranny or worse. Since a lot of people bounce on the rev limiter when attempting it.
-It's not hard to learn, if you know exactly what you have to do to do a perfect NLS(no-lift-shift). I can bet it would take numerous time's for someone to actually master it, go ahead, try it next time you're driving. I can bet $100 that you fail. (This comment is for anyone, not just the OP, and Im being sarcastic about the $100 bet btw)
-I agree that you don't have to know how to NLS to be considered a good driver. But if you're into street racing it could help you out a ton. Help you out at the track too. On a turbo car, you would hold boost through out all the gears(how ever many you use).
As a side note, no lift shifting is super fun!
