Apparently Jewish extremists in Israel think it's more important that the ranks of certain occupations (like firefighters) be kept free of girls and their cooties than that firefighters actually be able or allowed to do their job - save people. Think about that: sex segregation is more important than human life.

That should be sad and disturbing to any morally mature and healthy adult, but it also shouldn't be any sort of surprise to anyone who's been paying much attention to what extremist religious ideologies teach. Whatever the religion, one thing is consistent: obedience to the will of God is far more important than human suffering, human happiness, or human life.
So if obedience to what God wants causes people to suffer, too bad. If obedience to what God wants prevents people from being happy or from being equal, too bad. If obedience to what God wants even causes people to die, well that's too bad as well. And this is why such ideologies must be opposed, criticized, and pushed back against - they are a real danger to society.
Firefighters on Wednesday, responded to burning garbage receptacles in Meah Shearim. When some of the locals realized one of the firefighters was a woman, they began pelting her with whatever objects they could find. She was injured in her back lightly after being struck with a bottle.

The comments on that article reveal that the people involved in this incident are not alone in their views and attitudes:
There is no shortage of men capable of firefighting. Women are unnecesary and it is untznius for them to do it.
Also:
Women do not belong in the fire department. And that has nothing to do with Yiddishkeit or Judaism, even. It is a simple safety issue.
Then, of course, there are many Halachic violations with a woman being in the fire department. To start with, wearing the fireman's uniform and pants. And that is just the tip of the iceberg.
There's really no difference between the attitudes of these Jews and the attitudes of Muslims who want women to be covered in burqas from head to toe. The details may differ, but the underlying attitude is basically the same. Sadly, Christians aren't too far off from this these days and they seem to be getting closer all the time.

The US has women firefighters, so what safety issue is the problem?
When “deeply” religious people come to the realization that their religious superstitions apply only to them, the world may hope to become a better place.
