Really, because to me it equates more along the lines of when people wear a weighted vest or ankle weights when they go for a walk or run to increase the benefits of their workout. I've yet to see any negative impact on my round because I'm carrying my bag. I play with people who use carts all the time, I don't think anything is wrong with them using a cart. I don't get self gratification from carrying either, I just do it when I feel like walking. Also it's one less thing to mess with when I get to the course and before I leave. Besides, as I said, the nice carts like the ones Erik posted are much more expensive than I'm willing to pay when I at least one or two more clubs to get fit for.
I'm not going to pile on here but I'd suggest this be taken offline to PM's or actual live discussion. I don't believe the instructors here have done anything wrong and in the end it's just getting more personal and less about your swing.
Do NOT use clickit golf, they are a sham. Most of the courses they list do not accept their coupons. They encourage you to purchase 'Clickit Cash' (these are advance credits to use later), and then when you try to use the credit they are not accepted anywhere.
Also, they never answer their phone or respond to support emails. Try it yourself. (803) 802-3513.
