There's a huge difference between zionists and Jews. Judaism is a religion and Jews are one of the people of the book. We should respect Jews and interestingly enough Muslims and Jews are more similar in terms of worship and laws than Muslims and Christians. Judaism as the oldest of the three Abrahamic faiths (Judaism, Christianity and Islam) and has a long and rich history which we should respect. Bigotry and hatred against Jews solely because they are Jewish is unIslamic and disgusting.
Zionists are many times atheist and don't even have to be Jewish as there are many Christian zionists. Zionism is more about politics and nationalism than anything else. It's very important not to assume that all Jews are zionists as there are many, many Jews who hate zionism.
