When we think of religion, we tend to think of beliefs. But with any set of beliefs comes a set of actions. Certain things are good, thus encouraged or commanded. Other things are bad, thus discouraged or forbidden. And some people differ on how widely their religious rules apply.
Some faiths manage both.
Judaism holds that the laws of the Bible apply only to Jews, and that only the seven laws handed down to Moses 4 apply to all humans. Thus, for example, Jews must keep kosher, the rest of humanity is not required to. As long as your practice of your religion doesn't harm anyone, you are free to engage in it. Your beliefs may be influenced by others, but what you accept, and what you reject, is entirely up to you. Ultimately, you choose the path you will follow, for good or ill, and so does everyone else.
