"The inherent vice of capitalism is the unequal sharing of blessings; the inherent virtue of socialism is the equal sharing of miseries." -- Winston Churchill
There are a lot of arguments about whether communism, socialism, and liberalism are the same thing. What shouldn't be arguable is that they're all closely related branches of the same tree. If you don't want to live in a house made out of Aleppo Pine, you probably won't like a Coulter Pine or Eastern White Pine house either. However, since socialism has failed so often, socialists of every stripe bend over backwards to disassociate themselves from the many other disasters created by their ideology. Still, a pine by any other name is still a pine.
Socialism is particularly dangerous because it's so perfectly suited for the modern era. It's the ultimate "miracle" product: it's "nice," it's "fair," it'll make you feel good about yourself, it'll "help" people who "deserve it" by taking things away from people who "have so much" they'll barely miss it. It sounds wonderful, doesn't it? But, like most products with sleazy salesmen and hidden track records, the promises socialism makes are all a mirage. Since our schools do a terrible job of teaching history and economics these days, it's our job to explain how socialism slowly, insidiously eats away at the core of a society.
