Why did Hinduism never become an 'organised' religion like Christianity or Islam?

Ram, Ram, Ram… Punjabi tum adharam ko dharam kar rahey ho aur dharam ko adharm. Ganga mein ashnaan kar ke aao varna shamba ji tumhen kabhi maaf naheen karen ge. Aaj kal ke modern bachey, kalyug hai kalyug…

The varna/caste system as practiced is rooted in the Rig Veda.

How can you not say it’s not from the Hindu religion unless you reject the Rig Veda and other scriptures which enjoin the caste system.

Pls substantiate the Rig Veda reference.

Btw, who is “shamba ji” ??
