I've had this issue too. Mainly around politics. I wanted to engage with people outside of my political spectrum. I found that I could ask them what they believed and sometimes that would get a little bit of a response but often even that resulted in a hostile response. If you don't speak the lingo and agree with the people you're talking to I think online conversations just don't work that well. I've had far better luck in person. I think we are just not wired to debate online with strangers, in a civil way. We have to have face to face conversations to challenge ideas.
