Jews are an ethnic group, culture, and religion, but not a race. It's a common enough misconception spread via the media. Also any given Jew is not necessarily all three.
The lesson from World War II is that war can only delay the spread of an idea, but not destroy it. Ideas have to be fought with other ideas. Killing Nazis only bought us time to think of better ideas, spread them, and deradicalize people. Thanks to conservative propaganda networks and social media, we're on the verge of a fascist takeover. We are in an information race against fascists. The fascists are turning the US into a christofascist dictatorship, by controlling the narrative and driving the news cycle, not by killing anyone. We have to beat them in this race to stop them.
