I have little doubt that most people have atleast heard the name Ayahuasca, but do you know what it is? Ayahuasca is a powerful spiritual medicine prepared as a drink by the indigenous peoples of the Amazon. It's made from the Banisteriopsis Caapi vine, the Psychotria Viridis Leaf, and Chagropanga. It's praised and known for its very strong hallucinatory effects, and psychedelic experiences that surpass anything known to the western world, producing a truly profound spiritual and life changing experience. 

The conversation started with the situation going on between Isis and Jordan, and Obama saying something about how Islam is in actuality a very peaceful religion. That's not true. The two most popular religions in the world - Christianity and Islam - who are built on love, have evolved into the most violent. 

I mean really how can you argue with that logic? 
I believe, undoubtedly, in my God. My God says this, this, and this is truth. My God says I should do X,Y,and Z - and even promises me victory and blessings in carrying out these duties. Furthermore, according to my God, when I have accomplished -fill in the blank- I need not be worried with issues of morality or right and wrong...Because what my God commands is moral, what my God says is right. 
There is nothing further you can do to persuade that person in any other direction. The popular attitude of modern religion is blind faith. And that is faith in what you believe to be true, despite everything else. Things like logic, reason, free thinking, and any kind of doubt is seen to be a sin, or dangerous to the believer. So by definition, nothing you say can persuade the thinking and logic of a person operating through blind faith. 
And I'd like to point out, I do not think Christianity and Islam are the only religions whose followers can succumb to this kind of thinking. Contrarily, I believe every religion (or any kind of group / gathering) can have extremest. It's just these are the two religions we see these people originating in the most, because they contain the largest amount of followers.
The fallacy lies in the perception. A person, armed with the authority of the faith they have in their God, and driven by the perceived commandments of a Divine prophecy - can cause irrevocable, devastating destruction.

And I believe this gives way to a psychological condition afflicting the larger part of the religious community, that I refer to as the Persecution Complex. If a religion (Christianity) prophesies of its followers suffering persecution, and gaining grace through the suffering - then this creates a need to feel persecuted. (Christianity has the most followers in the US, by a lot, but claim to be the most persecuted in the US). If a religion (Islam) promises great rewards in the after life for selflessly being a martyr for God in this life - this creates a need to feel martyred. When you are practicing a religion with blind faith, there is no other option than for a Divine prophecy to be true in every aspect, so obviously you would do everything in your power to make it true.
