I've always said that a uniquely evil thing about Islam is that it reflects its founder, who was evil. It is not Islam;'s critics, skeptics, or even victims who have given us the information that Muhammad was a lust-driven and murderous man: it is in their very own Koran and Hadith, they celebrate it! And consider him the ideal man, worthy of emulation. This makes Islam very deeply pervaded by evil.
However I must emphasize how pervasive evil is. Cain was no Muslim, nor were the nations wiped out by the Flood when only Noah and his family were deemed worth saving. Neither were the German National Socialists Muslims, who carried off their most spectacular successes of evil in the heartland of historic Western Christianity, and with the actual cooperation of millions of those "Christians." And then we can speak of the atheist Communists, who carried out their 100-million-corpse depredations in the name of the Progress and the Brotherhood of Man!
My point here, is that when we speak of serious, hell-worthy sin, my assertion about "Anyone!" could do this is absolutely correct. Check your Bible.
I can say that even while putting Islam in a special category of evil in today's world, because of their being the aggressive cult of a slave-trading, lecherous, bloody-handed delusional fanatic called Muhammad.
Of course, anyone is capable of any sin (the very definition of total depravity), but not anyone subscribes to a “moral” code that enshrines such depravity as a standard. Looking at it from another perspective, sin can become so pervasive as to become one’s identity. In order to change, its adherents must turn away from everything that they have believed. Muslims who have left the faith understand the cost. Those who look for a protestant-type revolution in Islam are kidding themselves.
As are those who pretend that any Muslim country, sect or person can be trusted—anymore than communists or Nazis. Would we have allowed Nazis and Communist revolutionaries to establish cells in our country during WWII or the Cold War? Why should we do so now? Should we have expatriated the remaining residents of Dresden or Hiroshima, invited Mao or Castro’s “students” to take up residence in our country just prove our compassion? To deny evil is to welcome it.
