  Isn't about the only reason a non-Jew would convert to Judaism, so that they can marry a Jew?   Although admittedly the majority of converts do do it for this reason, there are still a percentage who convert because they believe Judaism to be a religion that appeals to them. Some of them may feel that it's right to convert. There are quite a few converts at my shul, and a friend of mine I met there named Barbara (in the conversion process) is converting because she's religious but rejects the concept of Jesus as the messiah. Oh, and on the offspring will be half semitic thing - how so? Do you consider Ashkenazi to be semitic - weren't we Mongrols and Fake-jews to you? How about if a convert married a convert? Their children would be totally white then. However, they'd be jewish.
