Oh, that's in wordy diatribes from all over the left. We already know about the antisemitic, anti-American garbage being issued from the likes of antiwar.com. Here's one tiny example of their neo-Nazi, anti-American European connection, if you can stand to read it.
"Eurolegal Services"
"US Neoconservatives"

(antisemitic Euro-crap behind the link)
Tom Metzger's bunch was way left. David Duke renamed his organization to "EURO."
"Neo-conservative" is name calling against all who support Israel (the multitudes of Christians who are in favor of Israel surviving) and who disagree with neo-Nazism.
Oops--correction of my own writing:
Where I wrote, "the multitudes," it was meant to say, "including the multitudes." The "neo-con" name calling is primarily against Jews but also used against all who support their right to live and have their mandated homeland.
The designation "neoconservative" was originally given to (or IIRC adopted by) a group of people who had become disenchanted with Democrat Party liberalism, primarily in foreign policy. Specifically, in policy toward Israel.
Most of the original neoconservatives were Jewish, and "neocon" was soon used by the opposition as a antisemitic epithet.
