False analogy.
The “source” was a USA Today/Gallup poll; polls do not translate to facts. (We certainly saw that in the last election.)
No, it was a perfectly good analogy. Let's go back to your post #78:
By asking for the “evidence to the contrary”, you imply that you do trust the source.
You can't defend that, it is obviously wrong. The message can be evaluated without considering the messenger.
My point was not to defend Mr. Will, but to point out that his critics here did not bother to present any evidence that he was wrong.
...polls do not translate to facts
They often do. The final Gallup poll before the election showed Romney 49%, Obama 48%. Not bad, and not biased against Romney.
If there is a good quality poll showing that young people oppose gay marriage, I'd love to see it.
That Gallup gay marriage poll data is in line with my personal experience. I live near a college, and I talk to a lot of college students. I would guess the percentage of students I talk to who are in favor of gay marriage at about 70%. To them it is a civil rights issue. I disagree with them, but that's not the point. The point is that they are young and that's what they believe. Of course, that's just personal, anecdotal evidence. High quality polls provide better quality data.
At this point I suppose I am obliged to to state clearly that I oppose gay marriage and I hope the Gallup poll is wrong. However, unlike posters here, I am not going to criticize Will for reporting bad data unless I have evidence that it is bad.
