I don't like it, but I would be interested to see the resulting map.
(normal Atlas)
I'm utterly opposed to a civil right being granted to a minority based on the good will of a majority vote (even then you've got a batch of the Liberal right who won't vote for even IF the plebiscite passes... I imagine even afterwards you'll end up with people saying "well 57% isn't that big of an endorsement... who'll speak for the 43%" etc etc). It's a disgusting, expensive, dangerous and unnecessary process, but Malcolm Turnbull's complete lack of a spine or being willing to stick to what should be core Liberal principles means this probably is the only path that will give them legitimate cover this term.
I am always opposed to referenda on SSM for the exact same reasons as you, but if it turns out to be the only way in which it can be implemented during this term, then I guess the referendum should happen. Not a good move strategically on the ALP and the Greens to oppose it, even if I totally understand why they did so and sympathize with these reasons.
