A very good question - it made me think. It opens a dozen other questions about what is exactly in the heads of the questioners?

How do women feel when they are asked questions like this - because women are better at open-ended questions but are regularly shot down if they don't follow the obvious line.
How long have women experienced the differences, and when did the dual standard first appear? It's clearly sexist in origin and partially patronising because it harks back to days when women were not educated. When was it first recorded and by whom?
Some of men's behaviour grew out being raised to respect women and in spite of women not appearing as equals, women were accomplished musicians and were expert needlewomen and pastrycooks. They were superb at 'their' work that men admired , Very few women had idle hands - many trained horses, milked 50 cows and raised 15 children.

The trolls pick up an ancient fragrance from the past and are still running with it. Like the men troubled by feminism, it's they have lost the the previous status of being special because they were male.
