IMO this is very twisted logic. So if you don't shout, you start beating people up?
Actually to me, it's the opposite. Once you start going down the path of "you have to express your negative energy in forceful ways", the logical conclusion is a bit of physical violence here and there.
Maybe you go from shouting, to whacking a table or slamming a door or pushing something over to express your shouty point, to getting a bit pushy or handsy in the vicinity of the other person, to sometimes laying hands on the other person, etc.... After all you can't help letting out what you feel!
Definitely not saying all shouters end up using physical force, but I'm sure the opposite is true: everyone who's violent at home also shouts/verbally abuses. It's all part of the "express all negative feelings, let it all out, you don't need to control yourself" school of thought.
Don't get me wrong, when really pissed off, I also want to shout at and sometimes hit my DH/kids/etc. I think most parents/spouses have felt that flash of physical anger welling up.
To me though, you don't just shit in the street just cause you feel like shitting. It's normal to lose control (shout, hit, etc), but to frame it as healthy is a bit weird. It's emotionally incontinent and there are better ways to express yourself than shouting, raging, hitting.
