If you want to know how far religious nationalists will go in pursuit of what they believe must come to pass, read the book of Joshua. Not only does it document serial genocides and recount that history as "good", Joshua 1:18 quotes the people answering Joshua's command with "Whoever rebels against your word and does not obey it, whatever you may command them, will be put to death." Yes, that is right, irrespective of the command no matter how illegal or vile, the supporters of the god-nation will kill anyone who disobeys the state.

No, that was not a quote from the Quran.

Did you hear about the time when a reasonably friendly group wanted to "lie with" Jewish women, and the Israelites told them they needed to be circumcized first? and they all got circumcized at the same time, and 3 days later when they were in the most pain, the Israelites went in and slaughtered them all?

Or what about the time when they said they were attacking Hamas underneath a hospital, except that the proof was a complete joke and easily rebutted, and so what actually happened is that they simply destroyed an enemy hospital? Yep, that just happened.

By their deeds you shall know them.
