Socialism is not left wing extremism even from already-right default view in US. Its of course up to definition what that word actually means, but one could roughly say ie current France and Spain are socialist countries.
It normally means strong social & welfare state, massive workers protections and so on. Nordics could be also labeled as such. Economy is not that performant and often utterly lost when some bigger changes happen on markets, with corresponding economical under-performance.
For extremism, look at proper communists or neo-marxists (aka forced mass takeovers of private businesses and any non-small private properties/ownerships by state, bloody revolution & rule by proletariat aka new elites). There is not much economic performance to speak of.
