> Online I am connected to those whom I socialize with or am otherwise professionally connected to. In the “real world” this constraint is largely absent.
This seems entirely backwards to me? Maybe you talk more with strangers IRL than online, but I doubt it. I only have n=1 (me), but we are talking right now. Who knows where we live in relation to each other?
So much of politics is split between urban and rural environments. Those groups are defined by where they live, so I expect very few conversations in person between the two, especially about politics.
Is that hard to disagree with? I didn’t even know atheism was a thing until I was on the Internet. No one in my community was an atheist and the media we were provided didn’t reference it much.
Personal anecdotes aside, we're mostly terrible at dealing with new ideas when they conflict with stuff we already know or is close to our identity. Remove the human element of the connection and we're even more likely to dismiss said conflicting ideas outright as stupid (I'll try link to that research). It's not hard to imagine how that might lead to strong yet poorly justified social division.
In the real world you are connected to people living and travelling around you, and that is not necessarily an unbiased set of people. It can be quite far from the average random group. You're still in a bubble.
