Umar Haque, 25, A teacher in east London, has been convicted of plotting attacks on gay bars and other public landmarks in London.
On Friday he was found guilty of two counts of preparation of terrorist acts and one count of collection of information useful to terrorism.
The extremist had been an Islamic studies teacher at the private Lantern of Knowledge faith school in Leyton, east London, and had also worked at the Ripple Road mosque in Barking, east London.
Haque kept a list of potential targets for ISIS-inspired attacks. A list of planned targets found by authorities in an orange exercise book included gay clubs in the capital.
Haque said he did not like Britain because of “mass fornication, mass illicit behaviour” – though the police investigation discovered that he had been searching online for transgender prostitutes.
A further two men associated with Haque were also convicted of terror offences at the Old Bailey last week. Abuthaher Mamun, 29, was found guilty of one count of preparation of terrorist acts. Muhammad Abid, 27, was found guilty of one count of having information about acts of terrorism. Abid, Mamun and Haque are due to be sentenced at the Old Bailey later this month.
