The world is changed by your example, not by your opinion.(But people are still really concerned that everyone have the correct opinions on everything! Or rather, have an opinion on everything, that can let everyone else know if you're on our team or their team...)
Follow up to that, from a FB discussion it spurred:
Vonnegut said: "Thanks to TV and for the convenience of TV, you can only be one of two kinds of human beings, either a liberal or a conservative." and I think it's even worse with Social Media.
And here's the thing: that's not even both sideser-ism. I'm a liberal, and I'm even liberal enough to think "my" side - while flawed on some issues - has its heart more in the right place of empathy than the "other" side, and that is an important moral and ethical difference. But it's like - you can't even give the other side the benefit of the doubt, any inch of that you grant to the other side is viewed as deeply suspicious by your peers, that maybe you're secretly one of them on the inside - as if the idea of "these are basically moral and not entirely irrational people who are living out some incorrect conclusions because of faulty starting premises and bad choices on what they choose to elevate in importance" is pure capitulation.
ALL human motion comes from emotion; the intellect itself is NEVER what gets the ball moving in any field, it just explains the actions, what the embodied-smarts of emotional thinking and muscle memory has decided to do. And so both sides are engaged in a war of riling up feelings, making sure those big momentum laden rolling spheres of emotion get going the right way. It's exhausting.
