World News Tonight, via the Wabac Machine

Here's ABC's e-mail promo for tonight's on-air report (online writeup is here) by Jake Tapper:

And -- who should have the final say about what gets taught to children: parents or teachers? A school outside Boston taught about same-sex marriage to kindergarteners. Jake Tapper has the story of one father who was arrested for taking a stand.

Pop the copy into the WABAC machine and set the dial for, oh, let's say 1972 and we get this:

And -- who should have the final say about what gets taught to children: parents or teachers? A school outside Boston taught about interracial marriage to kindergarteners. Jake Tapper has the story of one father who was arrested for taking a stand.

I'd be interested to find out whether Tapper, or World News Tonight could explain why opposing mentions of same-sex marriage constitutes "taking a stand," but opposing mentions of interracial marriage would not.
