Today while I was walking the dog down to the park, I threw out her poop, and saw a six pack carton and 2 empty bottles in there. Not the first time I've seen his empties. I guess they could be another neighbor's but I'm pretty sure they're his, it's his kind of beer bottles.
I'm very sorry you find yourself in this dreadful situation. Since you can't do or say anything that will stop his drinking I think you should decide, what are your boundaries?
Instead of attacking his drinking it may be a good idea to tell him that what he says and does hurts you and it must stop.
It's tough to learn that we're really powerless over everyone but ourselves. You can make changes in your own life, like setting boundaries. No one does this perfectly, it's a process.
