I recently joined an organization called Heterodox Academy. The website describes it as:
Heterodox Academy is an association of professors and graduate student affiliates who have come together to express their support for increasing viewpoint diversity—particularly political and ideological diversity—in universities.
The membership is ideologically and politically diverse, yet united by the above mission. I doubt if I’ll ever post anything on their site, but it is refreshing to see that academics from different political perspectives coming together to uphold a vision higher than just advocating one’s own views.
