Who is a Jew?

There was a conflict within a Jewish school named Jews' Free School in London. Apparently a boy applied to the school and was reject because the school claimed that he was not actually Jewish- when in actuality he is, his father is Jewish and his mother is a Jewish convert. The boy's family sued the school, claiming they were discriminating and the family lost the case. Although it was overturned later and the court now claims that the school was in fact being discriminatory. The court said that the admission should depend not on ethnicity, but on faith. The school has appealed this case to the Supreme Court, where they will make a decision on the case.

I think that the school not admitting the boy just because his mother is not Jewish is completely discriminatory. I went to a Catholic school and they would not look at the religion, but more at the academic achievement of a student. I think this is how all religious based schools should be. Further more I cannot believe that even though the mother has converted to Judaism, they will still not accept the boy as a student. They only claimed that they put those who are of full Jewish decent above all others. Hopefully in the Supreme Court case, the court will side with the boy.
