Why "/mute all" doesn't work

When dealing with toxic players, the common response is to just mute everyone on your team (or mute those who are toxic). I am looking for opinions on this because, to me, "muting all" makes the problem even worse. I find that muting makes me feel isolated from my team, that toxic players tend to get more frustrated when "nobody listens to them," and that the game ends up in a much worse state.

Any suggestions for how to keep game communication up, but removing some of the toxicity?
