Arabs used to go around the kaabah naked and worship hundreds of gods. Then they discovered the One True Allah.
The Bible and the Qur'an tells us that some Jews deviated, worshipped other gods, but the majority stayed with one G_d.
What have the deviants got to do with the majority monotheistic, Jews?
Oh yes, it fits in with the flat liner mindset that they are controlling the world and only by ripping off their 'human skins' will we expose the lizards beneath, now I see!
Insulting others is a sin in the Qur'an, now that you are aware of what it says, you have no excuse on Judgement Day when asked about it:
6:108 (O Believers) Do not insult the idols they set up besides God. They might insult God in their ignorance and hurt themselves. To every community We have made their deeds seem fair. Then to their Lord is their return and He will explain to them exactly what they used to do.
But maybe you are not on the right path and that is why you backbite doctors and everyone engaged in helping humanity:
33:48 And heed not the rejecters and the hypocrites. Disregard their insults, and put your trust in God. God is Sufficient as Guardian.
