How is it not her own fault for wearing dangerous clothing (a hijab) in a factory workplace? Something as simple as long hair can be dangerous in such an environment, and a hijab or scarf is unthinkable. Darwin award.
But on the other hand, there's religious freedom and rules that come into play. In this case though, if she didn't want to remove or replace the loose clothing, she shouldn't be allowed to work near dangerous machinery.
In case you don't want to visit quora, there's a picture of what looks like a tearaway hijab.
I'm a little unclear about your point. Do you mean that Moslems deserve to die, or low skilled workers in general?
It may be distasteful, but it has nothing to do with bias against a particular religion or against low-skilled workers.
