My opinion here: the left doesn't want to change "hearts and minds"; they want control. They can make their desired change in behavior last as long as they have power. They truly do not care about individuals (look at the history of governance and policy in democrat led cities - leadership that has been for decades: abysmal on every front) and their route to power is to turn groups against each other. But for that to be stopped, nearly all groups have to recognize that; groups on the left do not, from what I see.
Again, we are starting to see glimmers of change and I hope this grows to be a force that outweighs that of the dividers. But I will not unilaterally "disarm" in hopes the the other side will reciprocate. It's going to be small steps.
