Written Sikh principles (or for any religion) may sound nice but day-to-day believer behaviour is often the opposite. Sikhism is a young movement - only 400 yrs old - and a martial religion, based on war & violence. The culture behind it supports honour killings of daughters and child-brides. (In BC, non-profit agencies have large billboards on major roads leading into sikh neighborhoods shaming child-bridalism).   Khalistan effectively exists as a terrorist movement.
