You got that right!!!!!!!!!
Sikhs believe in one formless God and Hinduism believe in many Gods, now how can we be from the same religion, Hinduism is heavily based on the caste system whereas Sikhism rejects the caste system even though some Sikhs may practise it . We dont believe in idol worsip they do, we dont think a cow is any holier than a pig but they do. We dont believe in those meaningless rituals which Hinduism is full, a Hindu i know even admitted that. We have our own sacred text the Guru Granth Sahib which is remarkbly coherant with scientific facts. Sikhism preaches equality of women whereas in many parts of India Hindu girls are married off at an early age and some hindu women are even made to participate in sathi. Personally Hinduism doesnt really make alot of sense to me and the only thing i see that we have in commen is probably the fact that we both are dharmic religions and apart from that i would say we have more in commen with Islam.
Ps: im not saying theres anything wrong with Hinduism, im just saying it doesnt make alot of sense to me
