In regard to religion itself, like the other post said, he couldn't really care less and even advocated for Jews to convert to Christianity at a time, seeing it as another solution to the discrimination they're facing: "I see myself as an average modern Jew and I'm not afraid from the idea of a formal conversion to Christianity. I have a son, and I'd prefer converting today and not tomorrow so that his membership will start earlier and I can save him from the troubles and discrimination he'll face as a Jew".

There are other groups that could claim the same: Romany/Gypsies would be a big one but no one seems to want to claim a North Indian homeland for them; Sikhs might be another.
"I don't believe in god but he promised me this land 3000 years ago" sums up Zionism pretty well, or "Jews aren't safe anywhere so let's create a state by wiping out and expelling the native population and make enemies of all our neighbors". It's such a laughably self-contradicting ideology
Look, there's no way the coordinates this guy triangulated lined up with the religious site by chance. That would be similar to the odds that a flawed calculation of the age of the earth would turn out to be 6,000 years. If he had said anywhere else that argument might be right, but not of all places the temple mount, the one place in the world nobody would need any explanation for. If you're saying he was writing from a pragmatic standpoint, perhaps he argued that it would be convenient and more conducive to organizing power to follow along with what others believed: but that's still based on the religious thought.
