Did you vote for Kamala? Then you're not stupid. You did what you could, now we have to do more.
I disagree with the "voters are stupid" rhetoric because those people tend to ignore the Democrats' responsibility in their own loss, but if you read further, that's not what this person was doing.
Their central criticism is that people are lulled into more right-leaning positions by right-wing propaganda, which is true: the right wing has bought basically all media. Everybody takes marching orders.
So, people are stupid, but this is a deliberate move: stupidity benefits the right.
If by "appeasement of the right" you mean "accepting of the genocide," I will fault no person for caring about what's happening over there. If the democrats wanted to win, they should have let go of their psychotic, white-knuckle grip on the Israel military fund. It doesn't surprise me at all that this severely weakened their bid for the presidency.
That said, I can't say we're in a better position now with Trump. My hope for the people of Gaza now is either maga incompetence, or that Trump and Netanyahu make some kind of fascist quid-pro-quo deal not unlike the "Trump saves TikTok" publicity stunt.
