I'm normally pretty modest about these sorts of things, so it's probably not clear from my user page, but I have 20+ years of experience working in online collaborations, at every level from noob to big boss, and I'm trying to give you my best advice on how to be effective at changing things in WP. Personally I think WP will be equally fine with or without fair-use images, so it's not that big a deal to me either way - I just want the rules to be clear. Since it's you that wants to make other editors change their views, the burden is going to be on you to come up with the convincing arguments. It doesn't actually work to talk about "being pushed to the edge" - maybe it's true, but we lose editors every day for all kinds of reasons; only a prolific contributor with lots of friends is going to get any attention that way. Expressing frustration is a sign of weakness, shows that you can be outlasted in a contest of wills, and in this chaotic organization, willpower is everything. Attacks on the "ideology" put you in the "enemy of WP" category (perhaps unfairly, but that's how it works), and nobody listens to their enemies, not even if the advice is good. You've chosen a very tough issue to work on; it will require iron will, infinite patience, and no small measure of political deviousness to effect a change.
