So it's OK to "buck up the feet" (as Dr Spooner would say) and spoil the majority's enjoyment because you have a "right" to do it.
I think we all agree that it's a good learning experience for newbies, but you don't start exhibiting your paintings after the beginners painting and drawing class.
There's a right way to do it. I think we're talking about those who do it wrong (I include every other instrument not just percussion).
That's not snobbery - that's a reasonable expectation.
