Humphry's family background includes a number of Irish political figures:
- My great-great-grandfather was a Home Rule MP and Free State Senator. My great-grandfather was a Home Rule MP and Free State TD. My grandfather took part in an armed insurrection against the state in 1916. RIC Special Branch had a long file on him. My other grandfather took part in the allied capture of Iraq in 1917, and was then a colonial administrator in Iraq, probably in Hilla province. My granduncle was the first Prime Minister of Ireland in 1922. His son became Prime Minister of Ireland in 1973. My father put his political and religious ideas in the public domain, as do my brothers. Many other relatives have spoken and published on political and religious topics.
Humphry's has argued that the actions of Utoeya massacre perpetrator Anders Breivik are not consistent with Breivik's previously expressed counterjihad views:
- Should the counter-jihad feel guilt about this monster? Well, when he took part in public counter-jihad discussions up to Oct 2010, he seemed fairly mainstream. There is nothing that would make one call the police. He was right-wing and anti-jihad, yes, but he was not a neo-Nazi (he was pro-Israel) or a white supremacist (he opposed the BNP because they are racist). He was Christian, but not a fanatic (he was pro-gay). In fact he was apparently like me - liberal right. He was anti-racist, pro-gay and pro-Israel. So how on earth did someone like that become a terrorist against the West?
