I usually don't get into the antisemitism I have experienced in life, because it tends to make a person look like a whiner. I don't like when blacks do it, or when any other group does it, so I try not to do it either. I have little patience with cards, be they race, gender or religion.
But lest anyone think I have never endured antisemitism, I can tell you that when I was 10, I was severely beaten by a group of Irish Roman Catholic schoolgirls from the local parochial school, because "you killed Our Lord" (to this day I shrink internally whenever a RC friend innocently refers to Christ as "Our Lord"--I much prefer "The Lord" probably for that reason). It is a miracle that I ended up becoming a RC, but I did so based on what my Italian RC relatives had told me about the church; if those Irish girls had been my only experience, I doubt I would have become RC...fortunately I had the Catholic relatives on one side of my family to balance things out.
In junior high, a black Baptist student decided to organize a group to pick on me because I was Jewish. She would ridicule me for being Jewish, until one day, I looked her up in the phone book, learned her father's name was Theophilus, and told the other kids about it. Then she turned into the one being teased.
Once I found a pork chop strategically placed right under my locker. Hmm.
I was not the only Jewish kid to endure this; there were a few others too who did, but since most of the other Orthodox Jewish kids were in yeshivot (usually just boys), the girls had to attend public school (this was in the days before we had many Orthodox Jewish day schools).
But, there have also been experiences from other Jews, ones which I found very offensive. Because half my family is Italian RC and half is Orthodox Jewish, I've had a lifetime to see how each side thinks and talk about others. I never once heard a single antisemitic comment from any of my Italian sides many relatives. Not even one, amazing when you consider they left the church right after V2 and did not benefit from the "we love the Jews now" theology so in vogue in the RCC since V2.
However, on the Jewish end of things, I heard MANY comments, even directed toward my mother, a convert to Orthodox Judaism, whose level of Jewish religious observancy often put born Jews to shame. Yet they still would call her "shiksa" (derogatory term for Gentile women.)
My husband is not Jewish, and we currently live in an Orthodox Jewish community (not because its Jewish but for other reasons). I cannot tell you how many derogatory comments have been made to my face, because I chose to marry a nonJew...and not so much from the Orthodox Jews but from the non-Orthodox Jews, amazingly.
I have a neighbor who is not especially observant, but sees anti-Christian sentiment as his way to show his Jewishness. I had to stop associating with him because it was making me sick, especially his comments about "the Christian man-god" as he calls Christ. He had a bornagain Christian friend who was always giving him money when he was down on his louck, yet he still badmouthed his friend's religion to me.
My late aunt (obm) once called me in tears because RC schoolgirls came to her door, asking if they could clean her house or run errands for her. She asked them why, and they told her that their religion teaches them to do the works of mercy. She was crying on the phone to me, and said, "The goyim (Gentiles) treat me better than my own people!" I knew what she was talking about.
