They literally see us as some sort of intelligent but lesser being, like a dog or a child.
For a man like this, if a woman says something he disagrees with, he'll patronise her rather than address the points she made as an equal.
If a woman says something he think is clever, he'll explain to her why it's clever because he'll assume it was an unintentional aspect of her more trivial thought that his greater insight uncovered in her words.
But really half the time if a woman says anything it all he'll filter it out as trivial without giving it any thought at the conscious level, the content will get filed unattributed in his mind under "stuff", and at some point he may well make the same point himself and genuinely believe it was his original thought.
Yes, this happens to me a lot, and yes after 50+ years of this crap I'm salty about it.
