Not so! Many of us on the left favour individual freedoms, capitalism, profit motive, competition and so on, but not without some necessary restraints. It is, for example, possible to have rules that restrict individuals (you're not allowed to murder, or take somebody's stuff), without herding them. It is possible to have some rules in business and commerce (no monopolies, don't destroy the environment) without the state taking over ownership.
And here's the thing -- I don't think that "socialists" are even a majority of those on the left. In fact, far from it.
