Men do it more than women, - Fact
No idea, most of the men I interact with value my opinion.
Men have a different way of speaking, - Fact
Surely you mean women have a different way of speaking.
Men are more likely to be more competitive than women - Opinion, for discussion
Don't think so, I've worked mainly with women in an organisation encouraging women to succeed and they were pretty competitive.
Men talk over each other, are impatient and will interrupt and jump into a conversation if the other one pauses. - FACT
This is true of women, many don't even wait for a pause to interrupt and will move to a different conversation having stated their opinion. I have actually reprimanded someone for telling me I was wrong and she was right then walking off. (She was wrong and it was important).
It is about winning, and many of us had that taught to us since we were very young.
I think the days of the 'quiet' woman have been gone for some time but it helps serve a purpose to keep the idea going. There are many women (young and not so young) who are out to succeed.
