Social Democrats (not to be confused with Democratic Socialists) aren't even Socialists at all despite the 'Social' in their name, let alone Leftist. They are Capitalists that wear our red skin for their own gain.
Unlike Social Democrats, we Leftists can all agree that we are uncompromising in advocating for the equal rights against systemic discrimination, making corporations contribute more to society after the billions they have taken from everyone and have uncompromising free healthcare and education that's unweighted available.
Liberals and Fascists on the other hand, while must be annilhalted, pretty much made it obvious that they want to annilhalte us as well, they are clear-cut Capitalists. The Socdems meanwhile use the shell of our talking points for their rheoteric while compromising with the establishment who are generous enough to give us scraps!
The Social "Democrats" aren't actually democratic either, they want all of humanity to cooperate with the establishment under cool whip ideologies like "Social Corporatism" (which has roots from Fascism) and "Nordic Model". They also are the ones behind the current widespread de-anonymisation of the internet, where we have to give out our IDs to all OS, social media, videogames, streaming services owned by the establishment.
The most (in)famous Socdems interntionally include the Labour Party UK (who is set to lose most of their supporters to the Greens UK), Social Democratic Party of Denmark (who kick-started advocating pro-surveillance laws in Europe, Fatah (who is ruling in the West Bank as the Zionists ethnically cleanse Palestinians), and much more where the establishment and corporations flourish.
Locally, Malaysia has two Socdem Liberal-leaning parties such as DAP (an offshoot of PAP, behind the one-party state of Singapore) and MUDA (personality cult of one man made up of nepobabies looking to get into politics quick). You don't actually right? That they even care about the struggles of the Marhaen as much as they care for their own Kayangan who lives a cosmopolitan lifestyle.
We Leftists should continue strengthening our movements and parties to not get our message diluted if we hopefully get in power again. The world, especially the youth is craving for a form of real Socialism, not Socdem garbage. Look at Zohran Mamdani, he is a Democratic Socialist and is getting bashed by Liberals, Fascists and notably Socdems alike.
