So, let me get this straight.
Wearing a karda is wrong, while smoking is 'insulting sikhi' and what about wearing a person wearing a turban, while smoking is that not 'insulting sikhi'?
How about when a person goes to a gurudwara and the kirtan individuals start swearing at a person, is that not insulting sikhi?
How about when a person goes to a gurudwara and the gurudwara individuals close the doors, is that not insulting sikhi?
How about when a person goes to a gurudwara and the gurudwara individuals insult the individual every time, is that not insulting sikhi?
How about when a person goes to a gurudwara and the gurudwara individuals that provide false information to people, is that not insulting sikhi?
I don't know much but apparently, everyone else is more knowledge about Sikhism than I do.
Good Luck
