I don't think you can deprogram them. Social pressure is a pretty normal state for society, policing people is painfully average behavior.
When MSM & Social Media no longer have an incentive to apply pressure, then friends & family will also no longer feel the pressure to police others.
I don't think there will be a great "Oh I am so sorry, I was wrong" event.
I think buzzwords and major topics will just fade away as people find new distractions to waste their energy on, whether it's video games, movies or a new 50 shades of vomit, or what-have-you..
