Bullies need someone to stand up to them and defend the defensless. If not you, then who?
But what if in doing so you find out that you are the bully?.
it is not easy and I have learned a lot from it.
As for yelling, there is yelling and there is yelling.
Sometimes it is a release and sometimes it is degrading/bullying.
Domestic abuse comes under many categories, psychological abuse can some times be worse than physical.
But people fight and more often than not, when people fight they raise their voices and shout.
I would find it hard to believe anyone trying to justify psychological abusing someone by belittling them, shouting and generally being verbally violent.
But we may have different ideas of shouting.
