Israel is literally a parliamentary democracy. The “percentage of the populate” that cannot vote are people who are not Israeli citizens, primarily living in Gaza, West Bank, and East Jerusalem. There’s nothing controversial about this and it does not mean Israel isn’t a democracy. Gaza had elections until Hamas did away with them. West Bank has its own elections. East Jerusalem is typically considered part of the West Bank. This is a simplification due to disagreements over sovereignty, borders, etc. But it’s basically the facts that you claim are clear, and easily verifiable with a few searches.
