Domestic violence happens everywhere. Sadly it's something that runs in families: Children witness their mothers/fathers being abused and become abusers themselves. ONLY when it becomes reported can it be flushed out of the family, and even then it requires counseling and support.

Straight Arrow, abusers often don't seem like abusers at first. It might be years into the marriage before someone first starts becoming abusive with their spouse. but it's usually a downward spiral from the first incident. Sadly, a few years in, many men/women, regardless of the culture, feel they are trapped in the marriage, by children, financially or because of the social stigmas surrounding divorce, or from fear of further abuse (death threats, etc).

Domestic violence doesn't have a religion, a gender, a race, a culture or a creed, it belongs to everyone, everywhere.
