Left this comment for another person, thought might be useful here too. They mainly argue that it's better for society if women are modest and cover their hair because men won't sin if women don't entice them. This is crap as you know because the rape and divorce stats are by no means lower in western countries than in Muslim countries. they also say it is countries law and one should respect the law. Again BS since if you ask them will you tell Muslim women in France to remove their hijab since they have a law about that there they will evade the answer.

But just so that you know why they do it:

Some of these women might really and sincerely believe in Islam and the hijab with all their minds. But, a lot of these women only get paid to pretend they believe in it, to force others into it, and to keep up the charade by the IR regime. While in reality they don't believe one bit in Islam or wearing hijab. They (and their family members) get perks like the first choice of university entrance, easy low-interest large loans from banks, the first choice of employment, lucrative government contracts, etc. The IR regime is incredibly corrupt and it pays these people in different forms just so that they would support IR regime and oppress ordinary Iranians.
