the reason american leftists and liberals are rejoicing so much at this single act of propaganda of the deed is precisely due to their powerlessness. They have an event where they can imagine themselves and their sides the victors, but in reality it means basically nothing and will go away quickly.

You see this every time the American "left" is completely in the wilderness and feeling despondent and hopeless, they latch onto single events and act like there's a great savior who will come and redeem them because all they have left at this point is a sort of messianic faith as there's no practical avenues to power.

If Democrats had won the elections, the reaction to this event would be much more muted and the squishier left would be clutching pearls and rallying around Kopmala instead of dancing on the CEOs grave. Liberals like to act a lot more radical and anarchistic when they aren't in power but it's all posture.
