or left-center and still support free markets and capitalism.
Absolutely not. There is no such thing as “leftist capitalism.”
What is left and right is really simple - you are either for dismantling systems of power and privilege (left) or you are protecting systems of power and privilege (right). The (so-called) “center” is merely politics that performs the latter while pretending to sympathize with the former.
Believe it or not, it’s possible for a person to hold right and left ideals simultaneously.
No, it isn’t - you can’t be “half-pregnant.” If your politics protects power and privilege it’s perfectly clear what politics you ascribe to… it doesn’t matter what you may personally feel about this or that irrelevant little disagreement you may have with your fellow travellers regarding the details. A person that believes abortion should only be allowed “in cases of rape” is no less right-wing (ie, misogynist and patriarchal in this case) than a person that wants it abolished altogether.
