I don’t think it’s a discriminatory comment at all, it’s true unfortunately. Their culture is restrictive of women, so naturally a double standard will follow. The people who don’t follow those standards are seen as “westernised”, it’s the exception as opposed to the rule.
I grew up in a city with a large South Asian population and girls I went to school with would be scared of the most mundane things eg what their parents would do if they saw them with bare arms in public. I’m just talking short sleeved school shirts or school-issued PE uniform. Girls would literally wear one thing when leaving their house, go to an alleyway, and change clothes to wear a different outfit to school. Literally placing themselves in an unsafe situation in an alleyway to avoid their parent’s wrath.
Other cultures abuse women too, sure. However it can be a widespread norm in that culture to restrict women to such an extreme extent, in ways other cultures do not.
