Amir Abdullah: "The likeness of Islam and Kuffar is like that o f fresh clear spring water and water brought up from the bottom of a suburban sewer. If even a drop of the filthy water enters the clear water, the clarity diminishes. Likewise it only takes a drop of the filth of disbelief to contaminate Islam in the West."

No doubt a "true believer" and had read up on his Qutb.

From the great influential islamic scholar Sayyid Qutb's "The Right to Judge:"

It is not the function of Islam to compromise with the concepts of Jahiliyya which are current in the world or to co-exist in the same land together with a jahili system... Jahiliyyah, to whatever period it belongs, is Jahiliyyah; that is, deviation from the worship of One Allah and the way of life prescribed by Allah.
Islam cannot accept any mixing with Jahiliyyah. Either Islam will remain, or Jahiliyyah; no half-half situation is possible. Command belongs to Allah, or otherwise to Jahiliyyah; Allah's Shari'ah will prevail, or else people's desires: "And if they do not respond to you, then know that they only follow their own lusts. And who is more astray than one who follows his own lusts, without guidance from Allah? Verily! Allah guides not the people who are disobedient."[28:50]
The foremost duty of Islam is to depose Jahiliyyah from the leadership of man, with the intention of raising human beings to that high position which Allah has chosen for him.

No prizes for guessing how they intend to carry out the "foremost duty of Islam."
