Welcome, David.

I take your point that no-one can know the full value or internal qualities of a language (such as Esperanto) without tasting it on their own tongue over time. However, I do not think we can therefore dismiss all others' views on such a construction leaving commentary only to those with a vested interest either. That would be somewhat akin to denying me the right to decry murder just because I have never murdered anyone.

I agree with you about the relationship of language and power. Indeed that was one of my early points, in suggesting the almost accidental way in which forms of English have gained such worldwide pre-eminence:

The current state of English as the de facto world language is largely a historical accident of two major world empires having used the same core language. Other peoples now adopt it out of choice to enable their personal needs and dreams.
