Distributing condoms and teaching sex-ed is a violation of PARENTAL RIGHTS. Government schools have no authority to do that. But they also cannot tell parents how to dress their minor children. That is a violation of parental rights also. Hell, mandatory public education is a violation of parental rights in and of itself.
you are attempting, none to nimbly, to avoid the main issue here.
what of the young woman who, while wearing a thong, also chose to wear a knee-length, yet 'billowy' skirt ?
in the course of a dance, while executing some kind of spin step, the billowing of said skirt exposes the evil thong.
further, assume that the girl in the mini/grannie drawers combo is a wallflower type, and would have stayed true to form throughout the dance.
why was one subjected to public humiliation and the other was not ?
