I am a PhD student in computer science at the University of Waterloo.
My current research is related to Kolmogorov complexity. Sometimes I build robots, professionally or otherwise.
See my personal website colewyeth.com for an overview of my interests.
I appreciate the perspective. Personally I don’t really see the point of a secular solstice. But frankly, the hostility to religion is a feature of the rationalist community, not a bug.
Rejection of faith is a defining feature of the community and an unofficial litmus test for full membership. The community has a carefully cultivated culture that makes it a kind of sanctuary from the rest of the world where rationalists can exchange ideas without reestablishing foundational concepts and repeating familiar arguments (along with many other advantages). The examples you point to do not demonstrate hostility towards religious people, they demonstrate hostility towards religion. This is as appropriate here as hostility towards factory farming is at a vegan group.
Organizations (corporate, social, biological) are all defined by their boundaries. Christianity seems to be unusually open to everyone, but I think this is partially a side effect of evangelism. It makes sense to open your boundaries to the other when you are trying to eat it. Judaism in contrast carefully enforces the boundaries of its spaces.
Lesswrong hates religion in the way that lipids hate water. We want it on the outside. I don’t know about other rationalists, but I don’t have a particular desire to seek it out and destroy it everywhere it exists (and I certainly wish no harm to religious people). I agree with you that too much hostility is harmful; but I don’t agree that good organizations must always welcome the other.
