I think you are somewhat confused. These faiths are no where near homogenous internally let alone externally. The reality is this from denomination to denomination ideas, philosophies, and customs go from the mundane to utterly outrageous. For example you have Christian denominations that practice group sex, fucking with venomous snakes, and self mutilation. The names are really just jumping off points, and you can go anywhere with them. So how can anyone make a rational judgment. What the topic needs is a fair frame of reference. To be fair just pick a denomination within each religion.
Would it be fair to equivocate Islam with Wahhabi, or Christianity with Mormonism, of Judaism with Orthodox. I am just saying unless you narrow the parameters these names mean next to nothing. They do not even always share the same core beliefs. The reality is that these names mean nothing.
