Smells Like a Hoax
I am convinced this much-too-conveniently-antisemitic email is a self-serving fake. Why? Because it smells way too much like this, this, and this (among many others). Maybe I'm wrong, but conservatives should know enough to be skeptical.
UPDATE: In response to a couple of inquiries, yes, I DO think the hoax originated at ALG and that the burden of proof should be on them to demonstrate that it did not. That demonstration would need to involve an uninvolved, trustworthy, and technically savvy third party.
