I dont see the relevence of your first paragraph. Yes there is more than just 1 type of jew. So what?
Jewish power is a far right party with religious elements. It persuaded even secular young voters with speeches about a powerful country and far right ideas. Some people are easily persuaded by ideas of power. What else is new? But calling them nazi equivalents is a huge stretch. With all the bad things i can say about them, they are not nazis. Also, whether or not they are nazis is beyond the point here. They are definitely religious, they are definitely fanatics, and they are definitely not THE government.
And you completely missed the point - the political system in israel is one that gives some power even to smaller parties, such as Jewish Power and The United Arab List. They are not “in power”, they simply have some power.
For reference, they have about as much power as the arabic-islamic party The United Arab List had in the previous government, yet i never saw people calling israel an islamic arabic country.
