Personally I learned to interact with people in a nice way, even though I very much disagree with their strong opinions (if they don't have to shout their opinions every 5 minutes from the rooftops)
I believe HN meetups could work the same? Focus on the curious technical things and not on whether we like Musk or not?
I likely would have a look at the profiles of people who also go there (I just did for my area) - but if it is not a toxic troll, I don't care if there ever was something weird. I certainly have my strong opinions and topics that trigger me as well ..
