In order of appearance:
Judaism - central tenets: God is a mean old bastard, severe and largely unforgiving. And most people are cunts, so fuck them anyway.
Christianity - central tenets: God has mellowed with age, willing to forgive all sins provided you repent. And most people are cunts, but try to love them anyway.
Islam - central tenets: God is, on the whole, a blood-thirsty psycho. And most people are non-Muslim cunts, so kill them anyway.

Sadly, or fortunately no. Islam really is a special type of loony.
