Sounds like you have something rare and valuable.

Anyway, you make good points. From the point of view of society's health, it's good to create connections between people of different points of view, and this project could end up being harmful if it cloisters likeminded folks together. I would guess that many of the properties listed (such as being a musician or enjoying hiking) cut across fairly wide swaths of society, however.
