Study all peoples, all the languages, and all the cultures you can. Find out what people think about themselves, and ask each culture and religion
what they think about others.
You may find that all people like themselves, and may tend to
reify others,
downgrade them, and even project aspersions.
The important thing is to have enough self esteem to refrain from the negation of others as an instrument of your ability to contrast yourself as
"good," and the "other," as not so good. This kind of thing is pervasive, even consider the adversarial structure of our legal system. Minimizing
others is an institution in that case, and in many others.
One cannot be entirely certain what constitutes "antisemitism," but the term most commonly seems to originate from various Jewish attorneys and
groups, referring to any number of statements from other individuals and groups. It is used in so many contexts and parameters, that it seems to be a
magic way to win every argument and in the same adversarial tone as a court system, to destroy your enemies without much effort or proof.
Take the idea that Israeli newspapers criticize some governmental process or action, but when the same words are used here in the United States, you
may be guilty of antisemitism. So that is my argument, that you may never be able to eliminate "antisemitism," when it is defined by the Jewish
people, and applied to everyone else.
