I have a several close female friends who’ve flirted with Orthodox Judaism but not finished conversions to it. They look obviously goyish. They feel like conspicuous outsiders to the Jewish community, and they fear that they will always be viewed with suspicion, distrust, and dislike. So they wonder if this is really the world for them? It has become very clear to these friends what born-Orthodox Jews think of them and it is not good.
I understand their feelings, but I believe they will will diminish once my friends prove themselves by completing an Orthodox conversion to Judaism and then shouldering their share of the load in the community.
To convert to Orthodox Judaism is easier and quicker — in most instances — than completing an AA degree at a community college, but it still tends to weed out those who are not up to the task.
