What people are missing in this debate is that the need to be “contrarian” for some people stems from correction OCD. It’s not that your friend is “trying to be different” or “craves attention”—-it’s that they have a compulsive tic like biting their fingernails. Shaming them doesn’t fix their underlying disorder, it just makes you a bad friend to this person. Accept that they have this limitation (in your eyes) and learn to ignore it the same way you would with somebody living with Tourettes syndrome.
