I'm going to ask. How old are you guys? Seems to me teenagers are the ones who would completely over look where they were practicing and what they were playing through when they decide it's a good idea to start telling everyone the way it's going to be. Seem's that as long as the drummer was providing all of those things for you you maybe should have listened to him more. He brought more to the table than the rest of you.
Your best bet would be to also quit the band.
Then keep an eye out. The drummer with the PA and rehersal space will certainly be creating another project, he's heavily invested in this so you can take that to the bank.
If you are really nice and appoligise and tell him your willing to work together this time he might let you in the new band.
