Do your beliefs vary in other areas?
This is important, but hard for many to see right now: you probably have different beliefs in many areas. Maybe they’re vegans, and you eat meat. And yet, they don’t judge you for it (at least not that much). Maybe you’re religious, and they’re not. You’re still their friends. This COVID-19 thing is just one more thing that people have strong but sometimes different, feelings about. If you can try to categorize it as such (even though it probably shouldn’t be up for debate) you can think, “Well, if we can stay friends when we have those other differences, why not this?” That’s not to say that what they’re doing is correct. It’s just to say that, there have been other times you felt they handled something wrong. And it didn’t end the friendship.
