Playing basketball without wearing a jockstrap is beyond idiotic. Your grandson could injure himself.
I have nothing against nudity, it's normal and healthy-we were all born that way. But in the appropriate setting. Not everybody agrees with us. Their misfortune, but I don't believe I have the right to impose my personal beliefs on others. Collectively, we can, but individually we can't honestly or ethically do it.
If you want to understand Leftism -- and everyone needs to because it has been the most dynamic religion of the last one hundred years -- one good place to start is with San Francisco.
Or perhaps more precisely -- with nudity.
And even more precisely -- with public nudity.
Last month, the San Francisco Board of Supervisors voted by the barest (pun not intended) margin -- 6 to 5 -- to ban public nudity. By public nudity, the law refers only to displaying one's genitals in public. San Francisco women are still free to walk around topless. But that is not unique...
Wait!!! So long as we get enough people to agree on some measure, we are ethically allowed to impose our beliefs on others?!?!?! Interesting philosophy you have there.
