At no point did I mention volume, I implied education. I actually find just yelling louder to be worse than censorship, as all it does is increase the level of tension and push people towards extremes. Which helps no one.
I also didn't mean to imply that we shouldn't use band-aids at all, just that it's a simple treatment, not a cure. Blocking certain speech and rhetoric can help to a degree... but not if it's the only thing you do.
The problem with current strategies is that no one wants to go beyond that first step. Whether it's censorship, or shouting.
