When was the last time you met by strict religious people of other faiths?
Their limitations come from God, yours are man made cultural issues. They can not make the slightest amendment or change - that wold hurt their beliefs. You must accommodate them.
Why must I accommodate them? Because your god says so? No, that isn't going to work. Your god does not make rules for me.
BTW, I understand that you are faithfully representing a certain point of view here, and that it is not necessarily one you subscribe to yourself. My point is that no matter how fervently a religious person may believe that their directive from God takes precedence over any civil laws, "man made cultural issues" or other codes of any kind, fervent belief does not create reality, and "because my holy book says so" doesn't mean that people have to do it your way.
