I've been hearing people say that the broad left's various political identities are mostly just different stylings and have no practical meaning for a marginalized left. It seems to come mostly from the chapos and, whatever their value as polemicists, this is wrong. While I agree the factoralism is mostly silly, political difference is still essential because building up a young left is a political question. Also, the dismissal of it tends to come from dominant corners of any coalition.
