DaasYochid:
A chisurei mechs’ra is a last resort. I can just as easily say the
opposite – they want to benefit the tzibur and therefore they want to become MKs. The point is that none of us know what they are really thinking. We can speculate all we want. But I generally try to avoid imputing nefarious motives to people whom I don’t know. (This is an example of a statement that might be taken harshly, but I don’t mean it that way.)
The first reason presupposes that male MKs would otherwise be learning. Meiheicha teisi.
I already pointed that out.
Furthermore, it’s ridiculous to assume that those clamoring for female charedi representation are motivated by wanting more men in the Bais Medrash.
It would only be ridiculous because in practice it won’t result in more men in the Beis Medrash. It is certainly not ridiculous to say that they are machshiv Torah learning.
I can’t say how Charedi men actually view women and their opinions, but it is not surprising that there are women that perceive it negatively. Whether they should expect this particular tactic to work is a different story.
