4 Varna system of Aryan was pure flexible, a brahmin could become kshatriya, a shudra could become brahmin, kshatriya, or vaishya.
&
nowhere near similar to modern day rigid caste system which has more than 55,000 castes.
Caste was based on occupation & never was rigid. It became rigid during abrahamic invasion because of survival against brutality.
many new castes came into existence & many perished over time.
On top of that according to Aryan invasion theory, Aryans came from far away land, trampled upon many civilizations;
Yet so called caste system only exist in India but nowhere else,
also no documents, no literature, or any kind of proof related to so called 4 caste system was being practiced & forcefully enforced on natives is found.
& no one find it strange
Aryan theory is already debunked, many scholars were barking "Aryan invasion-Aryan invasion" but many new research kept proving it false & latest DNA studies did the same, based on which a christian scholar in India who was spouting "Aryan invasion", now twisted it to "Aryan migration" theory.
Many manhua openly propagate hatred is insane, they does the same with Japanese, how the hell they call themselves artists is beyond imagination.
They should be called "Beijing's Propaganda Artists" aka "BPA"
