The family's patriarch spoke with BET on December 13 about how he's encouraged his children to live on their own terms.

"What I do with my children, that I feel that the greatest gift that I can give my children is the freedom to be who they are," the "Collateral Beauty" actor said. "[My wife] and I are very serious about finding what they are, and encouraging them to be what they are because you can never be happy being what you're not."

Jaden, in particular, has been cruelly criticized for wearing clothes that have been gendered as "female." He's rocked skirts, flowers in his hair, and flowered jackets.

Will, however, is unbothered by the hatred. Instead, he's allowed his 18-year-old son to blossom as he chooses.

"I feel like a lot of times, when I was growing up, I would see parents force a child to be what you want them to be," he told BET. "As a parent, if it's an oak tree, I want it to grow as an oak tree. I'm not going to try to force it to be an apple tree."

In February, Smith told BBC Radio 1Xtra that he admires his son's fearlessness — and wishes others did too.

"Jaden is 100% fearless, he will do anything," he said. "As a parent, it's scary, it's really terrifying, but he is completely willing to live and die by his open artistic decisions and doesn't concern himself with what people think."

"The Fresh Prince of Bel Air" actor has also jokingly said that his children don't take his fashion advice seriously.

In a December 15 Facebook post, Smith wrote that Willow and Jaden showed him a vintage photo of him in a crop-top when he tried to say anything about their fashion choices.

"This is the picture my kids showed me the last time I tried to comment on their fashion," he wrote. "Haha! Last time I do that."

Raising children who reject gender norms is no easy feat, but Smith has made it look easy. That's the real reason why his parenting is admirable.

All children deserve supportive parents, but gender nonconforming kids, in particular, need it.

A 2013 article in Psychology Today lists "create an affirming home" as the top tip for raising gender nonconforming and trans children. "You can’t protect your child from everything, but the buffer provided by a loving and supportive family who accepts their children exactly as they are is the absolute best thing you can offer your children," the article states.

Will Smith has done that and then some. Can we clone him?
