So the Boston Globe is biased. It doesn’t make Romney’s tall tales true
Good point.
I can't begin to tell you the hundreds & hundreds of times I've seen the tactic you responded to exercised in FReeper posts...since posters can't or won't take issue with the facts, they go after the source...
If it's a liberal media source, the tactic is to go after them by implying "Well consider the source...must be 100% untrustworthy...you need to ignore these sources while we deny them."
If it's a conservative Evangelical source, the tactic is "Oh, they're just 'anti-Mormons' or they're just 'bigots'...you need to ignore these sources while we 'ad-hominen' them."
