What's your objection? That it's moral to be forced by law to wear jeans?

The law should not force anything. Western feminists should focus on improving women's rights in migrant communities, rather than calling people who point out real problems racist. Then more women actually do have the choice to wear what they want.

One of our elected feminists, Kshama Sawant did focus on migrant families issues, and passed landmark legislation banning discrimination based on caste.

Considering how many Indian Americans convert to a different religion for the sole purpose of escaping the social implications their caste ties them to, this is a good starting point.
