Shut up and obey the laws or spend you stupid time on earth changing itty-bitty, teenie-weenie laws that are there for whatever reason. Repeat;shut up.
Think if Trump get elected how much resistance he will face with in all phases of our country from people to military to politicians. He must not win.
I suspect these laws harken back to a bygone era when "modesty"- ie covering one's body from head to toe with heavy, ill-fitting garments- was so de rigeur that men found women's hair (the only part of women that they could really see; the only visible part that clearly proclaimed femininity, ie, different from men) sensual, if not frankly sexual.
Today, however, nobody normal cares about men seeing women's hair, because there are so many other, more blatantly sexual body parts routinely on display that hair arouses no particular excitement anymore.
