[Image ID: comment from @dougielombax asking simply "Strasserites?" presumably to ask after my usage of the word in the OP. Description ends.]
The original Strasserites were the smaller of the two major factions in the 1932 NSDAP, with the larger being the Hitlerites.
In theory, they should have been unable to work together. The Hitlerites were, after all, generic fascists with all of the anti-socialism that implies. The Strasserites, by contrast, were fairly hardline socialists who even specifically advocated an alliance with Stalin's USSR.
And yet, they were a crucial part of the Nazi electoral coalition. What could unite them?
Easy. They agreed on the fundamental cause of all of their problems: Jews. Where the Hitlerites blamed the Jews for inventing communism and the defeat of the German Empire in 1918, the Strasserites blamed the Jews for inventing capitalism and the defeat of the German Revolution in 1919.
"We have so much in common!" they both said, "We should do brunch!"
Either way, The Jews were nefarious puppet masters responsible for all stubbed toes (who, inexplicably, really couldn't manage to maintain any type of discipline in their ranks of minions, considering the existence of the other half of the NSDAP).
Ultimately, the Strasserites were socialists because they hated Jews, who they believed to control the banks and the businesses and all the capitalism stuff. As such, their socialism was innately subordinate to their hatred of Jews, and was quick to be cast aside if it should ever interfere with the Higher Objective. Hence, the alliance with the Hitlerites.
Thus, just as the Hitlerites famously prioritized Hating Jews above more practical concerns (like trying to stop the Soviet advance in 19-fucking-45), the Strasserites also prioritized their Judenhass above more practical concerns. Concerns like, say, protecting their vulnerable backs from the Long Knives of their allies.
As a random, non-specific example.
I use the word also to refer to the movement of wildly antisemetic Leftists, "Antizionists," who surged to such prominence after during the Simchat Torah Pogrom. These Leftists, to my surprise at the time, were fast to abandon any and all other principles they claimed to hold, from gay rights to saying-rape-is-bad, the very moment one of those supposedly-deeply-held-principles conflicted with the higher order objective; Hating Jews.
"Antizionists" were and are quick to make their common cause with groups that, objectively, embody everything they claim to oppose; from Hamas, to the Islamic Republic, to actively working to return Donald Trump to power in 2024. That this last would, of course, directly lead to Trump cracking down on everything-antizionists-claim-to-support, seems to have occurred to these laterday Strasserites just as little as it did to their forebears in the thirties.
Because, of course, all of those supposed principles of theirs aren't actually primary.
Modern Strasserites don't denounce the Patriarchy because they have any per se objection to misogyny. They do it because they think the Patriarchy is run by Jews. They don't rally against Colonialism because they have anything against, y'know, colonialism. They do it because they think The Jews are behind colonialism. They don't dislike racism, or homophobia, or transphobia, or any other tool of oppression on any objective ground. Ideologically speaking, they just happen to blame all of that stuff on The Jews, so they're against it.
If hurting the Jews means standing side by side with people who rape women to death, people who throw gay people off of buildings, people who literally enslave ethnic minorities... these Strasserites have proven time and again that if that's what it takes, then they will support all of those things to the hilt.
Correction: they will support all of those things to the last dead Jew.
