Yes, consciously being friendly is a feature not a bug. There are different types of communities. Read and writing here is high self-selvective and only appeals to certain types of people. There are many other types of people who are compatible with a rational worldview, who are not compatible with Less Wrong. Maybe they need more (literal) hand holding.

I think a big fraction of 'normal people' are compatible with a rational, or 'not obviously insane' culture. But that hypothetical mainstreamed rational culture (not existing now) is not Less Wrong culture. There are pieces missing.

Doing something to spread a more-compatible, more virulent, rational culture doesn't have to water down what has been established here at Less Wrong. This is about eventually Raising The Sanity Waterline, sustainably.
