I hope the original letter was written by someone from an exceptionally awful sub-community which is not representative of most of us.
This sounds to me like you are trying to avoid taking responsibility for a letter that you actually sign with your name. It might very well that someone writes you about a community who has nothing to do with the rationalist community and mistakenly labels them as such.
To the extend that there’s actually a problem that should be addressed it would be useful to be specific about which supposed sub-community the problem is about (as that would allow us to fix the problem in the sub-community) and I see no good reason to level the charge at the general rationality community.
