or would that be bad?
jeee. This answer is SO relevant to original question.
if you are considering nation as a unity of ppl living in one country - then yea, you are right. But i meant nationality as ethnic feature.
And there is no such thing as Jew religion, there is Judaism. and this is really funny that you not saying anything against the point that Jewish ppl is a race.
First of all Jew nation is not a race; you should put questions correctly.
There are few religious streams in Judaik religion. Orthodox Jews, for example, are the biggest rasists, and they have a special word for all non-Jews - "goy". So if someone dates goy - reaction of friends and relatives would be very judging.
Jew is NOT a nation. It's an ethnicity AND it's a religion. Israel is a nation. But not all Jews are citizens of Israel and not all Israeli are Jews.
That would depend on the person and the level of their belief in their religion but I do know that it would be bad but most Jews still do it
