Hello. I wanted to respectfully ask why Sikhs and Catholics aren't allowed to marry. I'm confused because I thought Sikhs believe that people are not defined by their religion ("There is no Muslim. There is no Hindu.") and they strive to protect people who are discriminated against because of their religion. I don't understand why Sikhs are discouraged from marrying someone of a different faith. Please, if someone could help me understand why, I would be very grateful. I am not Sikh so it's very likely that I don't understand Sikhism and that's why I'm confused. But please help me. I just want to know why.
