Why has Socialism regaining traction?

Yes it is but t's been given different names. Fact is the traits that make it up are being called for. Alexandra Ocasio-Cortez is not the sharpest knife in the drawer so she may not even realise what she's been calling for, but it's more state control & intervention and a lot more costly things being introduced including paying "income for those who don't want to work"

So what is the difference between Communism, Socialism & Fascism?
Well coon thought is Communism is extreme and bad, Socialism hasn't really been carried out properly yet but its good for everyone and Fascism is evil ultra right wing evil.

What people should keep in mind is what they have in common.

All are variants of Marxist dogma

All rely on brutal, ruthless authoritarian state control

All are against free thinking, freedom of speech, freedom of movement, freedom of religion.

All create an scary enemy in order to get full state control to neutralise the enemy and its generally a lie

Fascism creates a race/ethnic threat or a foreign power threat. Whilst it is socialist ideology it plugs into the receptive of the far right followers. It's about brutal authoritarian control.

Communism creates a class threat. Whilst it is socialist variant ideology it plugs into the receptive of the anti religion, anti wealthy class followers. It's about brutal authoritarian control.

Socialism is a authoritarian regime where the state controls everything too, it is receptive to those who're anti religion, anti God, anti wealthy class, its a brutal ruthless state of oppression.

They're all oppressive regimes where the state comes first and the individual does not rate at all. The individual has no rights or liberties, only the state rules.

A theocracy or caliphate is also an authoritarian state, removing all rights and choices from the individual and placing all citizens under a religion run authoritarian rule which is also brutal ruthless and like the others, more often murderous.

Cults are the same except they're pretty localised and not a Theocracy unless they're at a nationwide level.

Cult, Caliphate, Fascism, Socialism, Communism...you name it they're all blood thirsty authoritarian regimes that oppress their own people and if they refuse to live life as the state dictates they remove the objectors lives completely. They generally don't expel detractors, they generally kill them.

It doesn't matter if you think they're left wing or right wing, doesn't matter what they think they are.
They're all brutal murderous extremists. They're the easy door to the platform for crimes against humanity.

If socialism is so good, where's the immigration mass exodus type people caravan heading to North Korea, Venezuela or Sharia led Muslim caliphate countries?

So why is Socialism regaining support in Western Countries?
Who knows, it's completely counter productive and counter anything sensible.
I expect young people who've never lived through a authoritarian regime think its alluring to be subversive.

That or leftist academics are building up or we just have more idiots these days
