In my head libertarians are the right and anarchists are the left but they are similar in ideals (little to no government intervention). At least in the sense that if you talk to a libertarian I feel they tend to sound socially right and an anarchist tends to sound socially left. I have no idea if this makes sense at all. If you’re going to tell me to read more, sure, recommend some literature though.
Anarchism has the critical difference from other political factions in that, in one way or another, they don’t believe that a government with a monopoly on the use of force is necessary.
Libertarians usually think something needs to take on that role, if maybe at a minimal level, although if you add no government to a libertarian you get an anarcho-capitalist. If you subtract it from left-wing anarchism, you probably just get a vaguely progressive person.
Thats a pretty simple explanation, thanks!
