a) you believe in equality of opportunity (and are a leftist: a liberal, a democrat), or
b) you do not believe in equality at all (and are a right-winger: a conservative, a republican).
the idea of equality of outcome does not exist in the discourse. if it is mentioned at all, it is immediately rejected as extreme.
and, what that does is entrench a class hierarchy as beyond any kind of debate. we can talk about making it easier for people of colour to climb into the hierarchy - and then we label that "left-wing". but, we cannot talk about tearing the class hierarchy down.
so, when i show up and say "actually, this equality of opportunity stuff is a bunch of right-wing bullshit", it is immediately assumed that i do not believe in equality at all - because equality of outcome is not a feasible position.
there is no left in our society. there is merely degrees of the right.
