That's a matter of opinion, but I'll forego arguing it. I think the point you concede is one that's important: those who signed the Declaration of Independence were remarkable men in the final analysis; they don't need a glurge fiction to make them any more noble. When such fictions are allowed to stand, they only denigrate the character of the real people who founded this nation.
The debunking would have been more persuasive if they actually pointed out what the "glurge" was.
It didn't say anything was factually untrue, only that those men were "targeted", which is a very weak rebuttle. It seems clear Snopes was determined to prove this article false, couldn't come up with anything, and nitpicked instead.
