Your assertions are Rogaine-starved. As for the alleged lack of water on the Temple Mount, I suggest you study the Mishnaic sources on that, esp. Midot. You seem to have a lot invested in this. Are you always so profoundly affected by the History Channel or the like? “Quite a few” people believe they’re full of crap.
Thats nice. You keep your traditions, they have got you all into trouble throughout history. One being that under the Jewish people, the Temple was destroyed THREE times and one time being that the whole city was completely destroyed. So much so that eye witnesses wrote that if it were not for the rubble, nobody would believe that there was anything there.
Then the Romans renamed it for a time.
I wonder how they intend on rebuilding it on the traditional site while those Mosques are there.
