so·cial·ism
/ˈsōSHəˌliz(ə)m/
noun
a political and economic theory of social organization which advocates that the means of production, distribution, and exchange should be owned or regulated by the community as a whole.
"we want a real democratic and pluralist left party—one which unites all those who believe in socialism"
Socialism is basically a tool for forcing everyone to give. You couldn't get most people to sign if if phrased that way, so they pretend that taking from other is somehow charity instead of theft. Conflating the two also allows people to claim those that don't want the fruits of their own labor stolen greedy and immoral.
