I've seen many Sardar's that have long hair, yet trim their beard and then go out clubbing and still get respected by the Sikh community, yet if the Singh that has his hair cut does none of that and has much more respect for his religion (except for the hair cutting pair) gets not as much.
This is the unfortunate truth of sikh community.Large majority of them just want to see a turban and some beard and then you are automatically accepted as Sikh.There was hue and cry when when Cricketer Harbhajan singh walked ramp with his hair down,even SGPC objected that While the reality is Harbhajan shave/trims his beard,So when he was already not keeping his full hair why Sikh community objected when none of them raise objection When cut haired sikhs do something.
