First of all, I'd suggest dropping the attitude. You're not doing yourself any favours with the condescending and defensive tone you've adopted from the onset.
To answer your actual point, perhaps your crosshairs should be aimed at the UK, US and others' foreign policy. Saudi Arabia which adopts the most fundamentalist take on the faith happens to be a close ally to the UK and US. They weren't willing to reign them in on their brutal campaign in Yemen (and indeed provided them weaponry), nor when they brutally murdered US based journalists, so I doubt they'd have the appetite to tell them how to run their society.
