When I wore it at the age of 12 to 16, I was harassed by Muslim boys who got their non-Muslim friends to join in. If I didn't fancy them, they made it their job to turn my life into a living hell. Being staked out to be claimed by these little shits was thoroughly unpleasant.
And if I fancied someone else (who happened to be a non-Muslim, English guy)? I was actually called a "disgraceful woman" by one boy who knew it would wind me up, and he proceeded to say many nasty, misogynistic things about my character and accused me of pretending to be innocent in the clothes I wore.
The he tried to talk me into having sex with him in one of the empty classrooms.

My dad was shocked when I told him about a boy trying to talk me into sleeping with him, but when I tried telling my mother about the name calling (without saying "this happened to me at school") she was far more scandalised by the thought of a Muslim girl fancying a non-Muslim boy!
This is just ONE example of the harm of the hijab purity culture. Another is trying to constantly police what a woman should or shouldn't be interested in or WANT to do because of what she wears on her head.
