I hate to be the one to ask this, but aren't Jewish lesbians unorthodox by nature? I mean to say; isn't "Orthodox Jewish Lesbian" a self contained oxymoron of sorts? I have always found it amusing when people cling to a belief system that, in doctrine and deed, rejects them. I should predicate that I am not, in fact, well versed with the Torah nor am I current on my Orthodox Jewish law but that I have read the Old Testament several times over. While it is still a point of debate, most religions who observe the Old Testament tend to shun homosexuality openly due to the anti-homosexual sentiments to be found within the book.
For those who are not aware what being an Orthodox Jew entails; they are extremely conservative and adamant in observing all of the laws of Orthodox Judaism, letter perfect. That in mind, observing the extremely likely probability that they feel homosexuality is a sin* and that Orthodox Judaism isn't only a religion but a society and way of life; I fail to see how this type of activity would be plausible within that community.

*I am not completely sure on that one but it does say it in the Old Testament, then again, this is the same book that tells you that if anyone asks you to join a "false religion", you are to kill them with your own hand (Deuteronomy 13:6-11 (King James)) and that If your children are rebellious, you should kill them too (Deuteronomy 21:18-21)... :P
