Given the barbarous behaviour of those men that have gone to fight for the so called "Jihad" in the Middle East would seem to confirm there is something seriously wrong with them.
The jihadists who proudly proclaim that their "love of death is stronger than our love of life" certainly act in that manner as we see barbaric beheading, mass killings and other barbaric acts against all those who are considered infidels, kufir or satanic. In other words anyone that does not bend to their death cult.
Boris Johnson was reported in The Times (no link £) as revealing :
..the findings of of intelligence from Britain's security services that shows jihadists watch pornography despite their claims of spiritual purity.
If you look at the at all the psychological profiling about bombers, they typically will look at porn. They are literally wankers. Severe onanists.
Given that the ISIS criminals indulge in the trading of non-Muslim women as sex slaves there is certainly some truth in the premise that these jihadis are in fact losers, further repressed by a medieval theocratic outlook on life and extremely sexually frustrated.
Of course the usual suspects from easily offended brigade came out and condemned his comments. Why "leading members" of the Muslim community would feel the need to do this when anything that undermines the "street cred" of these vile men in their "community" should be welcomed, is frankly beyond me.
They are tortured. They will be badly adjusted in their relations with women and that is a symptom of their feeling of being failures and the world is against them.
They are not making it with girls, and so they turn to other forms of spiritual comfort..which of course is no comfort.
Of course Islam is itself quite backward on modern relationships and is inherently used to controlling its adherents. In the Wesern world they would percieve themselves as being "left out".
Abandon religion and...
Simply get laid.
Make love not war!
