He'll convince himself it isn't really a problem with 'normal people' ie middle class, until something happens to a woman close to him - dd or wife.
A lot of men are like that. An extraordinary ability to stick their heads in the sand and their fingers in their ears because it doesn't affect them.
Unfortunately, especially with DV, there's a fair few women like that too.
And before anyone accuses me of being a man, I'm a woman - and a mother. I know there's women like the above example because I have several friends who've experienced DV and they encountered women like that.
We can see examples on here too. I was on another thread where someone thought women didn't leave DV because they were "doormats" and "insecure about being single" whereas it's actually about lack of resources to safely leave and financially survive afterwards.
Also there's often loads of outrage - online, and protests, and in news reports - when a woman is killed or hurt by a stranger but much less when it's "a domestic". Because consciously or subconsciously people (falsely) think, when it's a stranger, "it could be me" whereas with DV victims "I'm not that type of woman".
As I said previously a major part of the problem is addressing it requires a holistic and societal approach - tackling the wider linked issues. The need for more social housing, a supportive benefits system, and better health, social care, and other support services.
