How do you ensure the economic power of say, gay people, when they can be legally fired from their job for just being gay? When they can't even visit their dying loved ones in hospital because they're not allowed to be legally married, never mind get tax benefits or inherit pension benefits etc. How do you stop a majority from punishing them economically and punishing others who try to help them?
Can you talk me through how your approach would have worked for the civil rights movement in the 60s or how the various law currently being drafted that legally prevent people from boycotting specific countries would affect your plans if used against your suggestion?
Once we've got more class majority equality, we can switch back to more focused issues.
Referring to "the left" (or "the right", for that matter) is more of the same. The people who are more receptive to a certain style of thinking and the political club that exploits them are not a unified group.
It's such a bad job that I wonder how much of it is intentional misdirection, distraction from the true issues.
