I think that's part of it, and part of it is that we curate real-life interactions a lot more than online. There are plenty of places I would never show up to / people I wouldn't talk to in real life (precisely because they would be the sort of people who troll online).
Whether that filtering is done explicitly or implicitly (i.e. neighborhood wealth)
Thanks for highlighting that point, the geopolitical filter,along with 'physical availability' (as you stated) are likely larger contributing factors than I had initially considered.
