I am not advocating that there should be women Rabbis. What I am advocating for is that if there are women who are motivated to learn Torah on a high level, then they should be able to be certified to answer someone halachic question. What happens after that is not my concern. If a person or a group feels that certain future steps are assur then let them say so and provide cogent halachic reasoning and there shouldn’t be any problem. At the very least, if you will not allow this certification, at least explain that it is not because it is halachically assur but as a gezeira to prevent future violations of halacha. Unless you actually believe that there is a halachic issue with certifying women as knowledgeable in halacha. If so, please read the mekoros posted here and respond accordingly.
As to the issue of advanced learning of Torah Sheba’al Peh, this has been discussed in many other threads, most recently http://www.theyeshivaworld.com/coffeeroom/topic/why-are-some-people-so-smart
Also, any sources mentioned here about women “paskening” would seem to take for granted that they are permitted to attain the requisite Torah knowledge to “pasken”.
As to the issue of public leadership positions, this has nothing to do with what I’m saying. If you (when I say you I don’t mean specifically YOU; I mean people in general) think that it’s problematic then come out and say that it is assur for a woman to have a public leadership position. There are women who speak publicly who don’t have semicha. These are two unrelated issues.
