It can't, because that statement about immigration is not true. Nor is there any official designation of a state religion. A 'state religion' is a different matter entirely from simply a majority of citizens being nominal adherents of one religion.
There is difficulty enough in seeking to communicate by 'printed' words only: let's not exacerbate the obstacles to discussion by being sloppy in using those words. Please, it will only make communication more difficult and distract from the discussion.
All Jews are allowed to immigrate to Israel. No questions asked.
No other religious group has such a benefit.
Jews who immigrate to Israel also get all sorts of financial benefits, that NO OTHER immigrants can get.
That's sort of the case. The state interprets "Jewish" to mean at least one Jewish grandparent. That has led to many many Russians sometimes fabricating a Jewish grandparent to get there. Obviously a person whose mother is not Jewish is not Jewish themselves, barring conversion. So the state has let in a lot of non Jews masquerading as Jews.
