JKDS and Wuf, just reading through the thread you two seem to be being intentionally obtuse at times. Like the "Legos haven't been around long enough for us to evolve" line should be looked back at as a red flag for you JKDS. A ton of evidence has been posted that points towards gender roles being influenced by hormones, yet your only response is "nothing is proven, and it either is cultural or hormonal, so 50/50" along with "here's an anecdote."

I'm not saying you're wrong, but your position as you support it is weak.
