The "idea" is that the carpet should match the drapes.

So you "feel like" you're a boy on the inside, but were "wrongly" born with a girl body? This makes you sad. You think you have a penis but there's a vagina. You have boobs but think you shouldn't & etc.
So to be happy you have to take piles of harsh chemicals & painful surgeries.

THEN you're a "happy real boy" even if your DNA says otherwise.

Now even before the "full operation" to chop & fix? You're still a "real boy" but only on the inside, therefor others should all kowtow to your insides or you'll be sad.
