I'm talking mainly about number 3. Nowadays, it's honestly just impossible to judge people based off different things. People are so different and there's just so much individuality that it's honestly really stupid to assume that because people might share one or two interests or characteristics, that their beliefs are the same. Even people that come from the same ethnicity or religion are all different. While they have the same beliefs, how much they're devoted to their culture or religion varies for each person. It's really honestly, illogical to make the assumption that all people part of a certain ethnicity or religion are all the same.
