Things I will no longer accept in a relationship: being yelled at. Period. End of story.
And for me especially if the yelling is accompanied by nasty name calling. With one partner I thought I was living with a salty sailer. However, we do often get frustrated in our relationships and under such times our voices can go up a few decibels. Maybe, we should invest in a decibel meter and set a top mark.
Very good decision... Increasing the volume is not a convincing argument...
Or a motivator
