I'm in my 40's, I agree that toys were in primary colours when I was a child and pinkification is new. It wasn't around until my second DD was born in 1997.
I think it's fine to have general sections as long as there is still Pink and Glittery toys about.
Just as damaging to the Female cause is making the majority Male choices as the default and "valid/better" one.
Let's work towards losing the Male anything as the "Ideal", that's been used for centuries to put women down.
Seeing Pink and Fluff etc as a lesser choice, or only a good one, if your child is male, automatically puts feminine women into third class position.
My three DDs have all had different personalities.
My eldest at 29, is in management and likes the Princessy/Barbie/TOWIE look on a night out.
She has the same thinking ability as her friends who make different choices. She is fully independent.
Already on this thread has there been put down comments about the choices some Girls/Women will make.
I think we should be respecting individual choices and leave the Stereotyping to the Misogynists.
