I think Islam is the only thing I've ever come across where the more I've learned about it, the more outraged I've become.
Although my experience is not as widespread as yours I have lived in Muslim countries and observed these cultures up close, not just from the comfort of my barca lounge and computer screen. The closer one looks, the more one becomes appalled by what is observable at all levels.
Islam is a medieval, monstrous system of religion embracing government, culture and law and without redeeming value. It is a crushing, totalitarian web of lies, deceits and oppressions disguising itself as something "holy". It is antithetical to the beliefs and values we Westerners are fortunate enough to hold dear.
