"They teach that the Iwama style is the only true style and that anything else you learn is garbage. The one thing they do say that I agree with, is that they got tired of all of the politics. "
Just an observation (because I have heard this in different forms from lots of independent dojos) isn't this an oxymoron?
Why? Most of the politic quarrels I have encountered in aikido seems to be internal affairs within an organisation or style rather than style vs style.
