This is grand advice! Throughout my life I have instinctively tried to find that "common ground" and present myself to others as an ally, that I'm really not their enemy, even though I may disagree with them.
Common ground is important in that it shows the "opponent" in any disagreement that there is a commonality of humanness, and to me, that is the most important thing to do in this sea of identity politics we are all immersed in (among the western world, I should say).
Thank you for this beautiful video, once again you've won me over :)
