Most people see Bitcoin as a granular topic within the category of investment. Therefore, that's the only conversation strain they'll humour it being discussed in (even then most people are closed minded about it) I see it as interwoven with many societal topics. And I know I wouldn't be taken seriously amongst friends if I tried talking about it within the context of, say, politics or philosophy. I have to then bite my lip many times to avoid being labelled as the 'crazy Bitcoin zealot'. My external is therefore non congruent with my internal, and that makes most discussions uncomfortable!
