variable scopes are simply not needed; are only a feature to increase sales to non hunters or hunters with little experience.

That's a massive generalisation, and I assure you there are plenty of hunters using variable scopes with lots of experience.

I certainly know that there are plenty of hunters using variable scopes with lots of experience, BUT IT DOESN'T MEAN THAT THEY ARE RIGHT. The scope sales people must really love them. However, I am not one to try to tell them to not use them. On the other hand, I know that I have no use for them. My "massive generalization" was learned through massive experience, my friend!
