That’s not how I perceivd the author’s take at all. He’s using the term “drool” purposely, describing the lamestreams.
From the article:
“A self-identified ‘community college professor’ on the left wing site Firedoglake uses a lot of Anglo-Saxonisms in ridiculing conservative reaction:
‘The wingnut attention span just isn’t that long, usually, and even by these cretins’ standards this “story” is pretty thin drool.’
‘Thin drool’ is priceless, isn’t it? The expression is ‘thin gruel’, but I guess this ‘professor’ has good reason to write under a pseudonym. There’s nothing more ridiculous than an illiterate calling others cretins.”
