Here's the thing. Let's assume you're Christian and I'm Jewish. And I say to you "What the hell is wrong with you? Don't you understand that your beliefs are ridiculous? Could you PLEASE forget Christmas - it's insane. Just celebrate Passover like normal people."
How successful would that be?
Correct. Zero. In fact, less than zero - it would further entrench you in your current beliefs.
So why WHY is Facebook (and every other outlet) full of people doing precisely the same thing - but with Republican/Democrat substituted for Christian/Jewish? Or with "current president/current not-president" being the opposing topics.
It has never worked and it will never work. Politics and religion are identical in how they are wired into the human brain and those brains are identical in how they process those beliefs.
At the very least one should post "Warning - Rant in support of X coming - if you're not in the supporting camp already don't bother reading. It's not meant for you."
