There is no Semitic race or ethnicity. There are Semitic languages that include Aramaic, Amharic, Arabic and Hebrew.
Antisemitism is racial profiling and persecution of Jews in Europe in the nineteenth century, and globally thereafter. Jew hatred, antisemitism, doesn't include hatred of Arabs. When Arabs hate Jews, they are antisemitic, even if their mother tongue is semitic.
Please understand this and put to rest that "We Arabs are Semites and therefore can't be antisemitic." Yes we can be!
Antisemitism is the hatred of Jews for being Jews. Disagreeing with Judaism or policies of the Israeli government is ok. Disagreeing with the existence of the internationally recognized state of Israel is antisemitism. Blaming Jews for imagined conspiracies, such as Jews control the US government, or all world governments, or global finance or banks, or media, or Hollywood are all untrue and known antisemitic tropes.
The Jews are not a secret cult that controls governments, finance or media, and don't run the world and conspire against non-Jews. Jews are like everybody else, they come in all sizes and shapes, agree and disagree on everything. They share a culture, common past experience, and most importantly, the suffering of unfair bias and hatred against them.
So please, stop trying to discredit antisemitism. It is real. The Jews lost six million in the Holocaust. On a per capita basis, that might be the biggest loss of any group throughout history. The Holocaust is the biggest dark spot on human history. Recognize it, and tell your Jewish friends that you understand the anxiety that they have inherited from their ancestors, as well as the anxiety that they suffer today because of similar Jew hatred.
And no, Islamophobia is not equal to antisemitism. There are over 1 billion Muslims globally and less than 20 million Jews. A muslim never feels like a minority even if living on the moon. Jews always do, unless they are in Israel.
We cannot realize peace until everyone feels safe. As long as the antisemitism injustice continues, there will be no peace, not because the Jews will be forced to defend themselves, but because all of us non-Jews continue to peddle the same hatred and pass it on to generations after us.
