You can be indoctrinated into a political party, a cult, or a belief system. In fact, all of us are indoctrinated into a belief system as we are growing up. Whether our parents or guardians are open and understanding people, or if they are bigoted, and want nothing to do with anyone outside of their own race and affiliations, we are subtly indoctrinated into their belief system. As we grow, many of us seek education in order to develop our own belief system.
