Completely agree, OP.
And it is a recent phenomenon, and it has been imposed by retailers.
Every single thing is gendered, not just clothes and toys. The sea of pink/blue is everywhere:
Duvets, pillowcases, wallpaper, curtains, backpacks, photoframes, phone covers, plastic plates, kids cutlery, water bottles, Wellington boots, umbrellas, candles, toiletries, bubble bath...
Kids cannot move a millimetre without encountering something that is telling them exactly on which side of the sex divide they belong.
And never the twain shall meet.
And when John Lewis decided to gender neutralise their kids’ clothing section people started eye rolling, and saying whatever next.
They entirely missed the point.
It frustrates me when people talk about transgenderism as celebrating diversity. Because it does the exact opposite.
It really is no surprise that kids are getting confused about gender.
A little boy who, quite naturally, is drawn towards something pink and sparkly (who wouldn’t be, we all love fireworks and rainbows), is soon getting the information, in no uncertain terms, that it’s for girls.
Despite the best efforts of many parents.
