Sikh is a special offshoot of Hindu that was created to fight the Muslims. That’s why they always carry knives.

Edit: it’s obviously much more complicated than that, but they are both Indian religions, both share many elements, but the Sikhs are the fighters.

They are different religions. One thing is the some Sikhs can be cool, they hate Muslims too. But like all Indians they can be total shit birds.
