In my experience, genuine "clashing of views" with amicable discussions happens pretty frequently on Mastodon. It's pretty astonishing to see sometimes, because it's so unusual for the past X years in online social spaces. Like, potentially-multi-day-threads of max-character-count messages discussing topics that people fundamentally disagree on but are trying to hash out each others' perspectives and "get somewhere" with it. Very interesting, and great to read. Sometimes it goes the other way and the people talk past each other, but that's pretty standard lol
