Ditto what dandy said. He might SAY he can see your perspective (and actually, he MIGHT see a bit of it), but the disease is much more powerful. It's not a matter of whether he wants to please you or for you to be happy--he may want that, and still be unable/unwilling to do what it requires of him. That's pretty much why I suggested learning a lot about alcoholism. It isn't so you can "fix" him or facilitate his getting sober--it's so you will understand what you are dealing with.
One important thing to know right off the bat, is that alcoholics cannot feel anything approaching "normal" without drinking. If you take that away--even if he commits to it--and nothing else changes, he will be miserable and unhappy unless and until he finds a way to live sober happily. And that generally requires a major overhaul of his entire being.
So it isn't as simple as getting him to see your perspective or be "reasonable" or "fair"--at this point I'd keep your hopes and expectations very low, because HE sees nothing wrong with his drinking. He only sees a bunch of people ganging up on him, trying to tell him how to live his life.
