Hasidic jews dating
I once received a message from a man who told me that many Jews do not like gentiles.
He knew this because his (Jewish) girlfriend's friends and parents disapproved of him.
I explained that these people did not disapprove of him because he was Christian; they disapproved of him because he was a Christian dating a Jew, which is another issue altogether.
This may reflect the fact that Jews who intermarry are not deeply committed to their religion in the first place: if something is important to you, why would you marry someone who doesn't share it?
For example, worshipping G-d in the form of a man would constitute idolatry for a Jew; however, according to some sources, the Christian worship of Jesus does not constitute idolatry for non-Jews. The word "goy" means "nation," and refers to the fact that goyim are members of other nations, that is, nations other than the Children of Israel.
There is nothing inherently insulting about the word "goy." In fact, the Torah occasionally refers to the Jewish people using the term "goy." Most notably, in Exodus 19:6, G-d says that the Children of Israel will be "a kingdom of priests and a holy nation," that is, a goy kadosh.
The word shiksa is most commonly used to refer to a non-Jewish woman who is dating or married to a Jewish man, which should give some indication of how strongly Jews are opposed to the idea of intermarriage.
The term shkutz is most commonly used to refer to an anti-Semitic man.
