I have an issue in their recommendation to use the Southern Poverty Law Center as a source to find out extremists. The SPLC is not a neutral source. For example, it has listed Aayan Hirsi Ali and Masjid Nawaz as anti-Islam extremists. https://mobile.nytimes.com/2017/03/28/magazine/can-a-former-... The SPLC is free to list whomever they want, but using their list to rank sites in Google search is very problematic.
Just read Maajid's section in SPLC's Field Guide to Anti-Muslim Extremists[0]. This is ridiculous; tweeting out a picture of Muhammad is 'offensive' to many Muslims and is therefore 'extremism'? They must be totally unaware of the rich history of Persian and Ottoman devotional art which depicts Muhammad.
