IME, since you haven't set up an rules ahead of time, you're getting pissed off is the worst measure of how and when a BL should act.
Why are you getting angry? You're the BL. You need to speak up as you go, and not wait until the NEXT time. The vocalist is exercising his right to free speech. If you have been silent, then he thinks you agree with him.
That really isn't the dynamic, but I'm not going to post a timeline of band events here. The next time, there will be a come-to-jeebus meeting between him and me, and if he doesn't like it, he's out.
