i agree with veer ghulam singh. to be a true sikh u do need kakras, but if others have 1 or 2, ask them in a humble manner, why u wear it? r u in a path of discovering wht sikhi is? r u interested to learn? share with them guru nanak humble way.....we are all a child of a same god, no matter we r sikh , hindu, muslim, gora or whtever. but if others are keen to know this path then told there hand and enlighten them. who know u might get a real love for sikhi out of that person!
think positive and shower the love....
