Low Hanging Fruit

Progressives know that the most fertile fields for subversion lie within the malleable minds of children:

With his blonde pigtails and purple tutu, Zach Avery, now five, has been living as a girl for more than a year - after he first refused to live as a boy when he turned three.
Little Zach was just three when he began refusing to live as a boy, instead choosing to wear pink dresses and ribbons in his long, blonde hair - because he has Gender Identity Disorder (GID).
And the primary school he attends in Essex has even changed the kids' toilets to gender-neutral Unisex in support of Zach since his official diagnosis last year, aged four...
...[when] He became obsessed with the girly kids' TV character Dora the Explorer and started dressing in girls clothing.

Take a pair of chuckle-headed, permissive parents, mix them with the sort of nutbags who are often attracted to careers in psychology, shake in some angst and cultural guilt, and three is now the age of consent in the UK. And Bob's your uncle. Or aunt, as the case may be.
Of course the comments section of this story is chock full of free love homosexuals desperately proclaiming the normality of this situation, and, by extension, their own.

I blame Dora the Explorer. The rotten little bitch.
