I just posted this conundrum at www.safercampus.org in response to a post entitled "Stealth Conservatives At It Again":
I'm very curious what would persuade you that FIRE is not "a far right organization." I see they have defended (among others) Ward Churchill, as well as a professor who posted an anti-religious cartoon on his office door, and a student who was expelled from school for his environmental activism.
Alternatively, maybe you consider defending free speech for all to be a "far right" viewpoint. Does that mean you think that the "left-wing" viewpoint should be in favor of censorship or political inequality?
Or, you might say something like "Yes, they defend free speech for everyone equally, which is a Good Thing, but they are still mostly right-wing in the rest of their lives." In that case, I would suggest that you should be glad that you and they agree on at least some things, such as freedom of speech and equal legal rights. (I also suggest the same things to my right-wing friends when we discuss the ACLU!)
[Oh, when I say I posted it, I mean I tried to post it, but apparently they didn't accept it. Apparently they are biased against logic and the truth.]
