To be a Zionist, you must acknowledge the historical, archeological, and genetic undeniable fact - that Jewish
people are an indigenous
people who originate from Judea (Now called Israel) and not just a
religion that you can leave. Therefore believing - that Jews, who were kicked out of Israel over the ages, can come back to their ancestral homeland.
Zionism has nothing to do with the Government of Israel or the plight of Palestinians under the current government of Israel. In fact, many Zionists in Israel and abroad disagree with the treatment of Palestinians.
