I'll agree most peoples first reaction is to take it personally, be offended and fly off the handle in some respect. There isn't an easy pill to give people at the start to help this, some are just that way, with a few naturally not.

However, being able to find and digest another persons point of view and/or humanizing them over a period of time through interactions does wonders. To some degree the polarization we see now in the US population and congress is largely possible because of groups becoming so split. We used to be able to discuss opposing sides of things and even while disagreeing on priorities, you could understand where the other party/person was coming from. Now we don't come in contact with the 'other side' often surrounding ourselves with like minded people, news programs, etc only affirming what we want to hear. At this point it's way easier to view others as 'pure evil' or malicious instead of somebody else with hobbies, kids, and other things outside of the topic itself.

Couple this with the average attention span of people being less than a goldfish, hence never willing to think or research longer than 8 seconds. This leads to a split of both sides yelling right past each other, seemingly the only thing in common being the belief that

Maybe if I say it louder it will be more true!

Lol. Even after all this I still try to maintain my hope for humanity. "Better" is never easy.
