I can go on Facebook, praise Hitler, and get likes. I think that skews peoples’ perception of what’s acceptable and what’s not. Maybe Facebook needs a way to give negative feedback.
It’s such a hard problem though. The quantity over quality friend groups everyone has now makes it difficult to trust others. When I was growing up, if one of my good friends disagreed with me it was a good indication I needed to reevaluate my opinion. I think that’s been lost.
