If it’s just going to keep getting worse and worse, what’s the final destination?
this is unfortunately what (mostly right wingers) decry as "bubbles" and "echo chambers", but I think if the left is going to win hearts, minds, and political power it needs to focus on engaging its own people on its own issues rather than waste time and energy endlessly fighting with the right.
also, inviting conservatives in to find common ground is largely a trap anyway, and has shifted the overton window a good deal to the right because people feel that "okay, maybe we can come to some sort of compromise". the writer a r moxon put it very well: "meet me in the middle, says the unjust man. you take a step towards him, he takes a step back. meet me in the middle, says the unjust man."
on the other hand, I've read that when people complain that their kids went to college and got "brainwashed with liberal ideas", what actually happened was that they met gay people, and black people, etc, and realised that most of what their parents were getting off conservative media was bullshit at best and hate-mongering at worst. so maybe the real solution is to welcome conservatives, but hold the line on making no space for conservative ideas and attitudes.
There's nothing wrong with having conservative ideas and attitudes. But are you able to express them without bigotry? Are you able to be pro-life without calling women sluts and whores, for instance?
The answer for some conservatives is no, including our president elect. Nobody is required or even expected to tolerate that, and in fact tolerating it only spreads intolerance.
