If the claim that was flying around the Internet at the time was that Rosenberg is a convicted terrorist, that's the appropriate one to address.
I certainly don't claim that Snopes is perfect, or that their choices never exhibit political bias or bad judgment. But I think this case is an odd one to pick as the key evidence that Snopes is untrustworthy.
This is intentional manipulation, they already know that most people read headlines (which are frequently the least accurate part of any story) and ratings fill a similar role.
Worse, they'll later compile the ratings into statistics and spread the misrepresentations further, all while claiming that technically in paragraph 7 they did admit the thing, which is why that's called a motte and bailey strategy.
So why should anyone attempt to prove that Snopes is following this rule when I have yet to see any evidence that this is, in fact, how Snopes operates, when even if we assume it is their standard, they don't appear to be following it very consistently?
That's a very odd burden of proof--asking me to prove that they follow a rule you just made up--don't you think?
