According to Yehuda Meshi Zahav the founder and head of Zaka (and a former Edah Chareidis activist) the answer is no. There are many more important issues that need to be dealt with. According to him this is a way of running away from the real problems. It is easier to address something like this then the more serious issues in the Charedi world.
The road to purity
Yehuda Meshi-Zahav, the founder and head of Zaka, was once himself coordinator of the Eda Haredit. Today, he says that this focus on the fear of being in contact with women sounds a little obsessive to him. "When I was a child, I used to take the bus from Mea She'arim to Mahaneh Yehuda, and I don't recall that anything wrong happened to me. I think this whole matter of buses has become totally disproportionate - as if there are no real problems elsewhere. So what if they see a woman on a bus? What can happen to them? When I think of the terrible things happening in some families - like the sort of thing we have been witnessing recently - I really think it's a way of running away from the real problems. Mixed buses seem to me the least of our concern," he says.
