Wikipedia is a fairly neutral source.

I mean, it's basically your bible, your one and only source for everything. Of course you think it's neutral. It's not, by the way, but you think it is.

Middle school teachers will tell you that tertiary sources are a good way to start your research when you apparently have no idea what you’re talking about.

That makes sense then, as it's obvious that neoliberals who only cite Wikipedia have no idea what they're talking about.

Oh wow, really digging deep for sources now.

Though even these sources basically confirm that it's a vaguely defended snarl word that can be leveled at anyone to the left of Bernie Sanders.
