Abdullah Quilliam: Britain’s First Islamist? at Yahya Birt
Yahya Birt demolishes the attempt to rebrand Abdullah Quilliam, the pioneer British Muslim of the Victorian era, as some sort of mascot for the pacified "British Islam" being promoted by Ed Husain. Quilliam was, in fact, pro-Ottoman - i.e. in favour of retaining the caliphate as it existed - and opposed to British colonialism, and was hated and attacked by the bigots of his day (in Liverpool) rather than embraced, as Ed and his chums are.
I think that Br Quilliam (if he was still alive) would be the first to slap down Ed's Islam isn't an Ideology theory.
In short, Quilliam was like Pickthall: another bigot and pro-imperialism as long as it was Ottoman imperialism.
Note though that Pickthall supported the Young Turk revolution, while Quilliam opposed it.
