Yes, you are right....i always hear our pracharaks guiding sikh boys not to cut hair/trim beards but nobody asks the sikh girls to accept the sikh boys as it is...this is the major reason (which now i understand) why many sikh boys trimmed their beards during the college days (i m from punjab, india), and to add to this our punjabi singers have set the trend (most of the singers trim their beards) which girls like and dream their partner to be like them which even make the things difficult for boys who keep beard....
