Beliefs are completely reasonable because they are in fact beliefs. Just like opinions and outlooks, everyone has different beliefs that make total sense to them. Just because we may or may not understand someone’s beliefs doesn’t make them unreasonable. A belief system is what makes up a person and the choices they decide to make. Every individual has their own correct beliefs, and saying that beliefs are silly or unreasonable is arrogant.
It really depends of what beliefs that person has like some beliefs may be really strict on a lot of things, others aren’t as strict probably one or two rules, but some beliefs can be both.
I like Sci-Fi. It's great how creative authors can get while writing them. I've read books like Last Day On Mars and Hungar Game, Divergent and a few other similar series. It's crazy to imagine what like could be like if you were in these books.
