Speaking down from a moral high ground obviously does not motivate everyone to do what we want, but it does motivate everyone ... a) it makes those who agree feel good for following the agreed rules b) it makes those who disagree feel like their human experience is invalid and motivates them to find a counter argument that feels just as strong (I HAVE to fight to protect my RIGHTS)
Obviously this is not the only thing that's going on. Every crisis is someone's opportunity.
