LINK to Guardian article, An insidious argument for censorship, by David Henshaw,
I haven't seen either documentary ("Undercover Mosque" and "Inside Britain's Israel Lobby"), but agree very much with what David Henshaw writes.
I consider myself a judeophile and friend of Israel, but to suggest that British (and American) Jews don't represent a splintered, but nevertheless very powerful lobby for Israel is absurd. Of course they do, and generally I support them.
However, I prefer my friends (Jewish or otherwise) to be honest and open, and not to intimidate their critics with accusations of racism or anti-Semitism, which, as the author, says, is an underhand attempt at censorship, of suppressing unwelcome views, questions or criticism, rather than engaging with them.
It is a classic example of the POWER of an assumed "moral high ground" used to control and manipulate society to one's own perceived (ideological, religious, political and/or economic) advantage, and as important today (though much diversified) as it was when the Catholic Church had a monopoly over it.
