It may be enough if we find common cause in wanting to be rational in some shared topic areas. As long as we can clearly demarcate off-limit topics, we might productively work on our rationality on other topics. We've heard that politics is the mind killer, and that we will do better working on rationality if we stay away from politics. You might argue similarly about religion. That all said, I can also see a need for a place for people to gather who want to be rational about all topics. So, the question for this community to decide is, what if any topics should be off-limits here?
