The amount of over the top righteous indignation in this thread..
Persuasion, motivation, “brainwashing” are real things that can be constructive or destructive depending on the leader, eg past and present religion and religious sects (let’s not go into those deep weeds) motivation, persuasion, groupthink being useful for various activities, some which could be construed as negative (can you think of any) Other purposes like service to family, community, self are positive effects.
Listening to the team (and some fans) I sense a little bit of “programming” but it is entirely positive.
Listening to politicians and their nutjob followers (and we all know people that are REALLY into politics in a scary way) it isn’t hard to see how things can go sideways if a critical mass of hate is cultivated.
