Hinduism explained

What is Hinduism ?
When a lot of religious people can claim or give a lot of explanations the truth is
Hinduism was a religion invented by the British when they first grouped people of similar idol worship when they made the first census. The first reference to the word Hindu is found in the Persian text .. some say Hindu derived from indos the Greek way of calling the people of river Sindh , however we find no reference to the word Hindu in any vedic text .
The word was Santana dharma. Which divides people based on Varna and caste.

Casteism is the very essence of Hinduism. As long as Hinduism is there, casteism would co exist. Casteism is oppression of lower castes by the upper caste, forbidding education, lower caste women weren’t allowed to cover their breasts, men weren’t allowed to enter temples never allowed to touch water bodies or eat in plates. They first born girl of the low castes were forcibly made devadasis and were sexually exploited.
When spreading Hinduism in the western world most upper caste hindus conveniently ignore casteism and spread Hinduism claiming Hinduism is a way of living. Any way of living that tells you to oppress others isn’t a good way.
Truly an outsider can’t become a Hindu. Hinduism is a pyramid of castes where one can never go up or down. One is born and dies in the same level .
When a white skinned foreigner converts into Hinduism which caste would he belong ?
He doesn’t belong to any so he’s not really a Hindu.
