People do this all the time in hobby groups and other social formations.

Right now in cycling the industry is pushing a new wheel size, and people are freaking out about it and saying they will ostracize people who buy a new bike with the new wheels. And every youtuber influencer is like making videos about how they will stay loyal to the old size... and they all did this over a decade ago and in a few years they will all be huge proponents of the new wheels once they are socially acceptable to do so, when it's established and no longer 'new and scary'.

Everyone desperately wants to signal to the herd they are part of the group, until the herd makes it acceptable to change your mind.
