I would like to know what "belief in Socialism" is even supposed to mean. It's not a religion or even a totalitarian ideology (though several of the sort have thrived under the umbrella name... but if any of those are what's meant, the answer is so obviously "lolno/lolno" as to... uh... I can't think of a fitting simile.)
By 'believes in socialism' they mean - 'dares not to believe in neoliberal capitalism'.
I think they mean more that one is an economic agnostic regarding their blind faith, not that one is actually a 'socialist' (atheist). Of course such distinctions are lost in their mush-brains.
