Oh, so you're an atheist too? I'm not surprised. Anyone who gets his understanding of Islam from Zakir Naik is pretty much headed for atheism. Nike, as we call him, or Mr Just Do It, is a low IQ neanderthal who can be demolished by any moderately intelligent teenager. He's anti-science, anti-freedom, and anti-reason. He preaches that non-Muslims cannot build places of worship in Muslim countries whilst crying about the fact he was banned from the West. Never occurs to him that if you deprive others of freedom, you will lose your freedom. He's responsible for the bogus Scientific Miracles in the Quran narrative which he stole from Christian and Hindu missionaries who made similar claims about their holy books. When you look up his quotes they bear no resemblance to any scientific theory you care to name. And classical scholars of tafsir never understood the Quran in that way. Even Salafis like Hamza Zortis and Muhammad Hijab have spoken out against this bogus narrative.Sounds like a trade to consider.
The part where I reduced toying with them about the incoherence of their idealogy and moral framework might have something to do with my own self-preservation as well. You know, the bit you said about that they would cut your throats in a heartbeat is true. So now I'm back to the point where even though I'm not practicing, I think their assumption is that I've 'seen' the light. It helps that I'm an adult now, so I don't have to interact with them anymore.
But you know, like @VixR I was a Salafi when I was young. I pretty much held any extremist belief you may encounter with them, and with some conviction. Things began to unravel because I loved science too much, and reconciling it with the Koran was too much of mental gymnastics. I realised I wasn't talented enough for the Naik-Yahya Olympics. But I can imagine if I wasn't into science or reading, that would have been me.
And when he does encounter a genuine scientific fact, like evolution, he claims it is a western conspiracy even though science trained Muslim theologians have accepted its validity. There's an arrest warrant for him by the Indian authorities who've banned his extremist nonsense. He will get raped in jail very soon.
