Talking about authoritarianism in Israel is useless as it suggests that there is something related to Russia or China or Cuba or Iran, but the reality is that the elections are pretty free, there is no rigging and it is simply people voting for programs they want.
I am sympathetic to secular Israelis(they are the economically productive element of the country) but I don't like the insinuation that liberal democracy is the only form of democracy, especially since Israel doesn't have a written constitution.
