Israel is democracy. Your claim about depriving votes from non Jews is totally incorrect. Every citizen, regardless of age, sex or religion has full voting rights and possibility.
You can check article on the subject in Wikipedia if you don't believe me at
http://en.wikipedia.org/wiki/Human_right… In Israel even parties denouncing the right of existence of Israel has rights to run for election (see the article).
From Wikipedia: According to 2005 US Department of State report on Israel, “[t]he law provides citizens with the right to change their government peacefully, and citizens exercised this right in practice through periodic, free, and fair elections held on the basis of universal suffrage...The country is a parliamentary democracy with an active multiparty system. Relatively small parties, including those primarily supported by Israeli Arabs, regularly win Knesset seats.”
In some instances, however, parties have been disqualified from listing candidates for election.
The Kach Party had run candidates under a platform which proposed forced transfer of Arabs from Israel and establishment of a theocracy in Israel ruled by traditional Jewish law. This platform was felt to be inciting of racism by the Knesset and was banned from participation in elections. In 1988, the Supreme Court of Israel upheld this Knesset decision. After a member of the Kach party slayed 29 Palestinians, the party was outlawed completely.
A concurrent 1985 decision to disqualify the Progressive List for Peace, a party which was founded to negate the existence of the State of Israel as the state of the Jewish people was conversely overturned by the Supreme court in 1988.
