I don't know about being "in the right" or not, but I do think this comment is correct in showing why it can be difficult, if not impossible, for some people to change their minds. I experienced this in my own family in regards to covid, which made for some very stressful discussions around masking and behavior when we gathered for the holidays during the pandemic. I live in one part of the country, where certain behaviors and beliefs around that were baseline assumptions, some of my siblings in a different part of the country, with the opposite baselines. To change minds would mean going against what all your friends, neighbors, colleagues, etc believed. It would mean pretty significant social distancing, unrelated to the pandemic.

We all were able to work out some measure of compromise for the duration of the visit, but, well, there's reasons we live where we live and not in the same place.
