I like how, before showing Sander on the snow failing, we see Dad skiing Chadly.
How the F can a little boy of four be “a little flamer”?!?
He talks about interior decorating 24/7?
Discusses being a bottom?
Quit sexualizing little kids, shit is gross.
Kids that young tend to "perform" the sex they are born with after they identify themselves with adults of the same sex without understanding what sex really means. Boys act like dad, girls act like mom. Not only they are able to identify some basic differences between sexes (they know mom gives food, not dad), but they identify them on themselves.
Which is not the same as saying they're experts on sex and gender like the Jennings implied about Jazz. It's more like "I dress like dad (pants, shirts), hence I am like dad" or "I go to the bathroom dad goes, so I'm like dad" and not "If I have a vagina like mom, that will make me a woman": they aren't able to think in this type of abstraction yet. The most you'll see is a boy wearing mom's shoes and saying "look, I'm mom", but his specific mom, not that he is a woman.
Sometimes they do the opposite, but it's more due to curiosity than because there is a real identification. These are the kids who could potentially be gay, but it's not absolute. There are other factors such as absence of a certain parent. It's indeed often a phase, but a continuous behavior could indicate a future homosexuality, in certain cases, not all.
