Examples of “far left” positions I’ve seen advocated online (as examples of what I consider actual extreme left positions to be like):
Forcibly deporting all non-Native Americans from North and South America.
Expertise is a lie, everyone is equal and all jobs should be assigned by sortition (aka, a lottery).
The housing shortage can be fixed by the people building their own housing.
People like nature pictures because of Western Imperialism.
Women are shorter than men because they are systematically starved.
Fixing issues like paralysis is bigoted.
Once the Communist Revolution comes it will endure forever with no need for enforcement, because no one would disagree with Communism without capitalist coercion and manipulation.
The only reason the USSR broke up is CIA subversion.
The people of Ukraine should be exterminated as fascists.
A nuclear war is desirable because Communism would inevitably arise from the ashes.
In my experience the far left has positions a lot more extreme than “gay rights” or whatever. That’s what makes them extremists. The reasonable, rational leftists aren’t “far” left, for the same reason; their reasonableness and rationality disqualifies them.
