Umm, that's not what non sequitur means. It means "it does not follow".
What does the Supreme Court and "Truth" have to do with me pointing out that the Annoying Christians planning to stand in front of Wal-Marts on Black Friday is another reason to avoid Wal-Mart?
I was right, you do need an adult to explain it to you:
There can be only "one truth", not "many truths".
Perhaps you subscribe to the libertarian idea that each person creates his own truth - (and all behaviours are equal and OK), and taking that tack you may as well rely on the Supreme Court to tell you what truth is, or NARAL, or Bill Clinton for that matter.
If there is no one source for truth, then how do you know that the things you believe are valid - 'cause they work for you? Go back in history and see where that mind set has gotten us.
