Something that I've noticed is that ex-Muslims are the most hate-filled, bitter, angry, people to leave any of the worlds religions.
Just take a look at the Murtads on this forum:
Making threads after threads, commments after comments, related to Muslims and Islam. They also have a bad habit of butting into threads for fellow Muslims discussing the Deen and inserting their, unwanted and not needed views.
It's like, deep down, they feel uneasy and not at peace with the decision that they've made, to leave Islam, and the way they live and know they've made a terrible mistake. Instead of them repenting and asking Allah for forgiveness, they let fear and anger overcome them, so the fear and shame of standing in front of Allah in Salah to ask for forgiveness, stops them. So they carry on with this weird mentality of mocking and slandering Islam, Muslims, Rasolullah SAW and even Allah, to make themselves feel a little bit good.
And it's not just a Somali Murtad thing, ex-Muslims of other races and countries do the same thing. I was once listening to LBC (a talk radio show based in the UK) and on a segment of the show, there was a discussion on Iran's nuclear issue. The show was literally flooded by these ex-Muslim Iranians, and all were saying how bad life is in Iran and how, "Islam destroyed Persian culture and history" and they were all calling for an ARMED solution to this nuclear issue and the West to have a forceful regime change in Iran, even though hundreds of thousands of their people would perish and suffer for decades to come, just ask Iraqis, how post Saddam Hussein is?
