String: If you google Theodor Herzl, Zionism, and Der Judenstaat [title of Herzl's pamphlet genarally accepted as the founding document of Zionism as a political movement] you will find that its impetus was political and secular, and only marginally, if at all, relgiously based. Israel is no more a theocracy than any other modern state with an established religion, to which it is not in any way mandatory to belong to achieve citizenship. There are religious political parties, to be sure, but plenty of secular ones also; religion plays no more part in Israeli political decisions and policies than does the presence of bishops in the House of Lords here in the UK.

And do for heaven's sake drop the tired dreary old bromide about how some people, other than Jews, who happen also to be ethnically Semitic can't be antisemitic in the accepted sense of the term, which in accepted usage applies solely to hostility to Jews. There are perfectly good semantic and historical reasons for this which only a dishonestly motivated hair-splitting maker of crass non-applicable debating points would ignore. Here eg is the opening of wikipedia's entry:

Antisemitism (also spelled anti-semitism or anti-Semitism) is prejudice, hatred of, or discrimination against Jews as a national, ethnic, religious or racial group.[1] A person who holds such positions is called an "antisemite". As Jews are an ethnoreligious group, antisemitism is generally considered a form of racism.
While the term's etymology might suggest that antisemitism is directed against all Semitic people, the term was coined in the late 19th century in Germany as a more scientific-sounding term for Judenhass ("Jew-hatred"),[2] and that has been its normal use since then.[3] For the purposes of a 2005 U.S. governmental report, antisemitism was considered "hatred toward Jews—individually and as a group—that can be attributed to the Jewish religion and/or ethnicity."[4]
