Hehehe, just wait til you find out exactly who they are working for and why Farsight left.
I can guarantee you that the current fluff of the Tau isn't going to change. Because GW is never, ever going to make any broad, sweeping changes to an entire race.
That's pretty much what is wrong with them, in a nutshell (that, and the gundam look). Shining paladins of tolerance and progress, if not exactly democracy, fit in the setting like a punch in an eye IMO.
But don't you get it? They represent what humanity could have been.
They're anything but democratic, they're like the political lovechild of Marx and Hobbes.
Democracy and limitation of powers was developed by humans as a recognition of our own failings. Give any one human unrestricted power, and sooner or later, he's going to abuse it at the cost of others. The Tau Etherals don't have that failing, meaning that a benevolent dictatorship can work.
They've completely destroyed any individualistic tendencies
What gives that idea?
The hints indicate that they were created by the great old ones.
I'm no expert at the fluff, but weren't the old ones long gone before the Tau even evolved into sapience?
