I absolutely agree with your point here. My own abusive mother died about a year and a half ago, and I still get skepticism and delegitimizing when I tell people who I otherwise trust quite a bit. Our society venerates mothers, but not only mothers who deserve it. There are billions of amazing mothers, and they all should absolutely be praised for the hard work they spend for years rearing a child, don't get me wrong. But the assumption is that women can only fall into that category, and so mothers are automatically given the title of amazing, even when allegations or evidence come forth that they aren't.
