twinklestein,
Yes, childcare is expensive. Most child minders are women. (Do you think that they have been forced into that career by men?) Surely you don't think they should be paid less?
You seem happy to accept that men "like to be dominant" Do you accept that that dominant behaviour may be due to the fact that men, typically, exhibit more aggressive behaviours than women? Why do you think they might exhibit more aggressive behaviours? Do you think it may have something to do with biology ie. hormones and genetics?
I do actually know quite a bit of history. I'm just wondering what the significance of the 4000 years you are quoting is because I've seen different time frames quoted by other feminists.
Re discrimination - I think you'll find that I said males of other species are unlikely to be discriminating due to 'social conditioning'. Do you think they do? Or do you think it is exclusive to humans?
I take it you're not a royalist then 
"Do you think all ancient cultures subjugated women? You may need to check your historical facts there."
The key word there is "all". Should I take it that you accept that not all ancient cultures subjugated women? That, in fact, there were some matriarchal societies?
"You think biology got men into positions of power? "
I was actually asking you how you think men got into positions of power. I, personally, do think that biology plays a part though, yes. Do you disagree?
