The Jewish Internet Defence Force (JIDF) is an unofficial online advocacy/hacktivism group for the state of Israel. Their website claims they are "dedicated to opposing jihadism and antisemitism on the Web" — though they really just hate Islam and want to see it wiped off the face of the earth.
The JIDF opposes all mosques. They castigate as hypocrites the opponents of the mosque near Ground Zero, on the grounds that mosques should be opposed everywhere, not just in Manhattan.
The JIDF's inflammatory attacks on Islam include "we are against ALL mosques, as they are tributes to the genocidal pedophile false prophet (idol), Muhammad, who was a murderer of Jews." They also condemned an imam for antisemitism for saying that Jews are "the scum of the human race, the rats of the world, the violators of pacts and agreements, the murderers of the prophets." The disconnect does not appear to register: their attacks on demeaning rhetoric are interspersed with demeaning rhetoric.
Advocacy for the group frequently takes the form of tattling violations of Terms of Service on various websites to remove antisemitic comments or sites, or drawing attention to the removal of pro-Israel comments or sites. Recently, the JIDF claimed credit for "taking control" of an anti-Israel page ("Israel is not a country, de-list it!") on Facebook and removing its members. It is uncertain if they help or harm their own cause.
JIDF members often congregate on the /r/worldnews subreddit of Reddit, and on the /pol/ ("Politically Incorrect") board of 4chan, where they can be seen bitching about non-Jews being patriotic. Users of /pol/ are highly paranoid, and suspect basically anyone whose views don't line up with theirs to be a "JIDF shill." In fact, it's rumored that if you say "Holocaust" three times on /pol/, a JIDF agent will appear in your living room.
