Anyway, the point was that the culture is what is important. Jewish culture is clearly somewhat different from Christian culture. If you seep a person in a specific culture that will define how they think in a way that their race does not.
Please, do not repeat this filth. It is anti-Semitic nonsense that there is are “Jewish racial characteristics”. Jews come in every shape and skin tone. I know a very nice black man who is an African Immigrant and he is Jewish.
There is no Jewish race - Judaism is only a religion.
Judaism is well accepted as being both a race and a religion. Of course it has fuzzy borders with people who don't believe the religion but are genetically Jewish and vise versa, but so does every race and every religion.
It's not helpful for thought to demonize an idea by calling it "filth". How can you consider possibilities if you've decided in advance what's clean and what's too dirty to even say?
Jewish secularism comprises the non-religious ethnic Jewish people and the body of work produced by them. Among secular Jews, traditional Jewish holidays may be celebrated as historical and nature festivals, while life-cycle events, such as births, marriages, and deaths, may be marked in a secular manner.
In fact, the term "Jewish people" refers principally to an ethnic group with a common cultural heritage and ancestral religion, not to adherents of Judaism. Judaism happens to be the common religion of the Jewish people.
