I'm one of these guys who always mutes everyone (I have VOIP volume to 0), here's why:

I like to play to chill out, while still playing objective, but prefer PvP (bots are way too dumb).
The in game cues (map, markers, comms menu and automatic speech) are enough to have a coordinated play without voice.
Also, people talk too much, sound awareness is very important in this game (I also still see when an enemy is talking next to me, I just need that info, not what he's actually saying).

I also was never votekicked nor tk-ed for my gun so I guess the OP is experiencing it because of the class (I only play rifleman).

Cheers
