Incessant repeating of talking points or catch phrases without realizing the conversation has moved beyond them, inability to acknowledge another's point and build from it (instead treating them as an ignorant person or an enemy in need of correction), way too much crosstalk, the discussion arc constantly stalling at trivial points where her emotions made her take an unnecessary stand on something no one disagrees with, forgoing diplomacy in favor of charged language, subtle accusations or outright personal attacks, the list goes on.

A woman's emotional, self focused responses can be all kinds of fun during flirtation and sex, but they're hellish to endure in anything resembling a debate situation. Change the subject or even create a distraction when such a situation arises, it will only make everyone within earshot miserable. Sometimes you can't avoid listening to a little ranting when you're alone with her (protip: do your best to ignore everything she's saying and appear as noncommittal as possible unless it's directly relevant to your immediate future), but if she gets going around other people and a conflict emerges, you need to either shut it down or walk away until it's over.

Women who do this are difficult to coexist with and are never going to be good relationship material for most guys.
