A large basis of their beliefs is actually on defending others. Much of what makes a Sikh standout (Five Ks and other garb) are reminders of this. I grew up with a Sikh temple on the corner of my street and in highschool my theology class assigned us to go out to a different religious ceremony and experience their traditions, worship, and speak with the community, so I spent some time at that temple. They were very welcoming, incredibly nice, and when I did my presentation to the class one of them came to school that day to show the class the articles of clothing and talk to the class about their faith. Since then I've always loved speaking to and meeting new Sikhs in my community.
