Don't be smug--be sympathetic. Talk to them about why they think this happened.
I’m so glad you (and many others) have included this part, because this is such a huge and important takeaway that gets so easily over-analyzed in online leftist spaces, and it’s exactly why I made this post.
The echo chamber effect will often have us losing sight of the actual goal, but god damn it just feels so good to be correct. That first hit of vindication after years and years of warning liberals that this would happen is euphoric, but extremely toxic if you let it slip into rhetoric.
Frankly, nobody likes to be wrong, and accepting that can take quite some time for some people. That’s why the most important thing to focus on is giving others the proper tools to analyze what happened. Being smug together can come later when they inevitably find themselves on the same side as you
