The solutions that I have so far are just finding groups of people who tend to be open-minded, and then discussing things from the perspective of "this is interesting, and I think somewhat compelling".

When I get back from vacation I intend to do more wandering around and talking to strangers about LWy type stuff until I get the impression that I don't sound like a crackpot. When I get good at talking about it with people with whom social mistakes are relatively cheap, I'll talk about it more with less open-minded friends.
