I well remember the "slippery slope" theory, it has been extended to people marrying more than one partner, marrying their pets etc.
I don't totally discount that thinking because I am old enough to remember when divorce was socially looked down upon. It was brought up in Reagan's first campaign for the Presidency. Now with the divorce rate at more than 50% it's just an accepted fact of life.
The birth control pill was controversial at one time too and abortion was not spoken of. Everything changes in society and not always for the better.
Please see my response to MikeInIraq.
Because the ERA was so vague it could be interpreted in many more ways that was "intended" (or maybe many more ways AS intended!)
Thank you for reminding those reading your post to remember Sgt. Maupin.
