“Or, you could keep whining about how these people have no empathy for you.”

When OP speaks of allies not being allies, it’s comments like yours that I think of. You use “we” like we’re on the same side here, but (ironically given you say this of OP) you have missed their entire point.

We’re not going to survive (let alone make progress) if we tear each other down like this. This isn’t me saying “they go low, we go high” nonsense, because you’re quite right that relying Trump voters to show empathy doesn’t look like a good strategy. I don’t see that OP was actually saying anything of the sort though. This is about how we (people opposing Trump and co.) treat each other. It would be easier for us to become practiced and educated if we could rely on the people who are meant to be allies.

I want to believe that you’re a decent person who wrote an assholish comment. It happens to the best of us. I hope that you’ll reread OP’s comment and your own and see how unproductive this approach is for everyone. But maybe I’m wasting my time here, in much the same way that expecting empathy from Trump voters is probably unwise. That’s up to you, I guess
