The biggest logical fallacy in this entire discourse is that the changes wanting to be made are dreamt up on a sterile whiteboard by 'language tinkerers' whatever the hell that actually means. The actual reality is that you have a substantial community (whether you want to hand wave us away as not being representitve somehow, a group of more than a handful of Lojban anything is substantial as far as I'm concerned) who is using the language daily, continuously throughout the day and have been doing so for years.
Those changes are the result of usage. Of finding what works and doesn't work for us as -users of the language-. What's happening here is that we would like to commit our findings back into the language so we can both claim to be speaking "Lojban" and so that we don't have to qualify everything as being 'official' or 'experimental' to the many and regular new comers that show up on our door.
Diminish and minimize us all you want. But understand it doesn't actually move your interlocutors to do so. We are aware of our own reality. If you're just singing to your own choir fine, but its important for the wider audience here to realize you're being offensively ignorant on this point.
No doubt - day to day - we sure spend a whole lot more time using and talking about Lojban than you characterize yourself to be doing. Please readjust your tone to acknowledge that the changes that are knocking at your door are legitimate concerns borne from -daily utilization-.
Regards.
