OK, I'm done. I've made the alternate arguments for anyone who wants to read them. All I'm trying to say is:

1) there are advantages and disadvantages to both modes of competing. Which is best for you depends on your circumstances and dancing goals.

2) it's dangerous to generalize. There are bad teachers, misguided students, and just plain obnoxious people in every variety of dance. There are also excellent instructors, dedicated students, and great people in every variety of dance. Look for the latter and avoid the former, in your dance studio and online.

I totally agree with your two points, Ellen. Thank you for the concise summary.

I danced in both Pro/Am and Amateur partnerships for over 8 years, so I think I have a good picture of both sides of the equation. Both have their advantages, both have their drawbacks, and both depend upon the quality of the instuction and the quality and dedication of the people being instructed.
