Some distinctions obviously have to be made. Seems as if we are not on the same page of what is being discussed here. We are dealing with 3 or 4 groups of people:
Does not know the difference between bowling pins and juggling clubs, calls both objects pins.
Understands there is a difference between the two objects, but are only aware of one word to represent them, pins.
Understands the difference, and uses the words clubs and pins to distinguish between them.
Perhaps there is a group 4 (but I think it is probably insignificant?)
Understands the difference between the objects, are aware of both the words pins and clubs, but insists on calling both objects pins anyways (to piss off jugglers?)
I will assume that we means jugglers here. Are you suggesting that jugglers somehow get together and decide over what word "we" should use when we talk about (the object formerly known as) clubs? This is not a possible scenario, I think? And I still do not understand what the problem is? Seems as if David thinks the audience generally thinks the clubs are bowling pins, but Thomas seems to think they know the difference, but are unaware of what word to use when talking about them. David likes to inform them of the difference, both in concept and in word to represent what they are, which I think is perfectly fine. Can you explain your problem further Thomas, sorry that I do not follow.
