While I agree in principle, I respectfully disagree in practice. My reasoning:
- As great as this forum is, it represents just a small portion of the total contra dance community and therefore is a partial voice
- Without magical powers, I doubt that even this forum will be able to agree on a term in a practical span of time (but would be delighted to be wrong on this). There's no effective greater "contra rules committee" to vet and set a term (I find this a strength, BTW). Folk process rules.
- I believe people (dancers included :) are more robust than this and deal with synonyms constantly in daily life. This is one call. Were we throwing all the terms in the air then that could be chaos - for returning dancers. Effective callers dealing with newcomers should be defining/teaching their terms as each is introduced over the evening. You might get pushback about one new term from ongoing dancers, but folks should be able to cope so long as you define it.
- The ultimate arbiters on this matter will be the dancers. In my prior life in business process work, I would witness long debates amongst the "architects" about what to call or name something and ultimately the users would just go ahead and call it what made sense to them - despite what the architects told them it should be. :)
