Eventually, you learn that this is a normal means of leading a family. The domination and the outbursts become a sign of strength, and when you grow up in that hell, you can see the direct result: They have control. Later in life, when your own relationship flops out a big ol' veiny conflict, you use what you've been taught: douche it right on up.
"I'll shit directly on your soul, you human toilet!"
... Or You Do the Polar Opposite:
Some of us are lucky enough to learn that the douchebag's system wasn't just wrong; it was abuse. We vividly remember the fear we felt when they were Massengilling up the joint, so we vow to never do that to other people. Unfortunately, many people who make that decision end up going too far in the other direction, avoiding conflict at all costs.
The longer that goes on, the more it seems like we're walling off or have become emotionally disconnected, and that's when the relationship really begins to collapse. But worse, if we continue bottling up and avoiding confrontation, it can eventually build until an emotional mushroom cloud shoots out of our heads.
