And no, it's not as simple as "they make mistakes, they learn." For one, regarding the education, these kids are NOT going to learn the value of an education on their own for some time because they'll be -- wait for it -- KIDS, as in the elementary school brand that by and large lacks the rational development to pass a short-term gain for a long-term gain in absence of parental development. The individual anecdotes you guys bring out are irrelevant. Maybe YOU were excited for school, sure, but it doesn't matter, because YOUR circumstances are NOT theirs. This is a complete absence of parenting on the issue, as compared to whatever values your parents instilled, except in the incredibly unlikely circumstance where you too were in the situation and made the right choice, in which case I hold you are not a human being but a ridiculously badass cyborg and cannot be expected to give accurate testimony for us mere mortals. ;) (But seriously, we presumably had parents that made us go to school or at least made sure we understood the value of an education, against the feeble short-term OH GOD WANT CHEERIOS AND CARTOONS that no doubt ran through our heads all the while.)
Left to their devices, the kids aren't gonna go to school until they're adults (or 'young' adults, again, 16-17, whatever), and then they're several years behind, if they even see it at all! That's YEARS of their one shot at existence down the drain in the name of 'individualism.' There are SERIOUS consequences to this, not a simple live-and-learn experience.
Regarding picking and choosing parts of the established gender roles, it's far from as cataclysmic. In fact, I would argue it's not as applicable. My complaint hasn't necessarily been with the practice, though I think for sake of avoiding bullying troubles and the like it wouldn't kill them to do like mapleleaf said: impose a gender role upon someone who literally cannot think for him/herself until they're more mentally developed and actually able to make a decision to protect them from the problems of an aimless child's mind, much as you protect from truancy or any other child's whim. Once they're hitting puberty, they're not only significantly more mentally developed, but they're also starting to feel the biological impulses of sex, so they'll have a *much* more complete view of what's going on. THEN you turn them loose from gender and accept whatever they choose.
But this entire postmodernist social engineering experiment is ignoring one HUGE fact that simply CANNOT be overlooked. It's applying a mindset that, while I think flawed, is at least functional with a MATURE, MENTALLY DEVELOPED, RATIONAL adult or nearing-adult human being, to a human being that is anything but. You CANNOT do that, practically OR ethically, and expect a good outcome. Plain and simple.
