TNT: Please be aware that this is a forum where people are used to debating things. That inevitably means that from time to time people will disagree with what you (and I) say. When someone disagrees with you that's not an end to the discussion...it's a beginning! It invites you to explain why you disagree.
Your statement 'Rudiments are called rudiments because they apply to any drum' is an interesting claim that deserves discussion. If you engage with my argument and explain your point of view, and I do the same, the chances are we will both learn something. For my part I will learn about rudiments and you might learn something about traditional west african djembe techniques. Win win I say
Another example is that you clearly think that by making a distinction between 'west african' and 'western' techniques one is putting oneself in a box. I think the opposite. I think that by learning another culture's music you break out of a box. This doesn't mean you have offended me, or that I am acting as some sort of 'culture police'. It just means we disagree. This should not be the end of the discussion...it should be the beginning, where we both explain our position and maybe....just maybe....arrive at a common understanding. You are clearly a very experienced drummer who has been playing for many years. I have lived in west africa for 3 years and have studied djembe for about 12 years. I'm sure we could both teach each other a thing or two!
In short don't be so easily offended and please keep the discussion going
