I was an Orthodox Jew until I was about 18, at which time I converted to the (traditional) RC faith. Due to many life changes and moves, I lost touch with a Tridentine Mass (and later, Byzantine Liturgy) near me, so I fell away and ended up returning to Orthodox Judaism, but my heart was not in it; I wanted to be a member of the true church, whatever and whereever that might be. So my identification as a Jew had long since ceased, maybe that's why I feel awkward when ppl introduce me to Jews who have become Orthodox, etc. I spent more of my life as a Trad RC than as a religiously practicing Jew.
Also, to be frank, I have some issues with Judaism and rabbis in particular, based on things I only recently learned about the reasons for the development of the LXX, and why the rabbis after the destruction of the Second Temple suppressed the LXX and came out with the Masoretic Text. That and a few other things angers me to learn that the rabbis basically lied to me and all other Jews, all in order to preserve a religion which by rights should have ended after Christ said, "it is finished" on the Cross, and when the veil of the Temple was torn in two....not to mention when the Temple was destroyed in 70 AD.
Its hard not to feel resentment when you learn the depth of the deception carried out by the rabbis of your own people.
