for me personally...there is nothing in the world, no argument or calling out of BS, that can be accomplished through yelling, abuse, or threats, that cannot be accomplished just as well in a civil conversation between mature adults :/

I wish I could believe this. Maybe I'm just really cynical, but even mature adults oftentimes have prejudices and biases that make a civil conversation unproductive. And of course there are plenty of adults who are not very mature. I think yelling, abuse, and threats have their place, if used in the correct manner. I.e., they're tools, able to be used for both good and evil. (Civil conversation, too, can be used for evil.)
