In my opinion, Jewish people (who are mostly Caucasian) do NOT "hate" Caucasians.
I think that many Jewish people simply do not like President Trump because they feel that he is not sensitive enough toward non-Caucasian people.
Jewish people had been treated very badly in Europe for centuries, so when they came to the United States, many of them felt morally obligated to advocate for the rights of other groups that they felt were also treated unfairly. So they became what we term "liberals."
And liberals include African Americans, Asian Americans, Caucasians, Hispanic Americans, and Native Americans. Those groups do NOT necessarily "hate" Caucasians. Some of them simply feel (rightly or wrongly) that they are not getting a fair shake.
