The real contrast between Islam and post-modern Christianity is how appealing Islam is to male nature. Liberal Christians have feminized religion to the point where men don't want anything to do with it. Islam is a lie, but it's a lie that is far more appealing to men and in tune with male aggression. A return to muscular, robust Christianity requires affirmation of male leadership and masculine virtue -- and a reacknowledgement of the old masculine virtue of chivarly: the strong protecting the weak, a uniquely Christian concept. We've done nothing in this society except denigrate and mock men for the last 40 years, then we're really surprised how men, especially men in prison who have been raised by single women without fathers, flock to Islam. Evangelical churches, with their emphasis on male leadership, are growing by leaps and bounds, not surprising to me, they are an antidote to our society.
That shouldn't be surprising. Islam is a rich man's religion. Take some time to read through the Koran, and you'll realize that Muhammed set up Islam as a way to organize society under the control of wealthy males, and supported by warrior males and subservient females.
Men have pride in Islamic society, and women have value. We may consider their male pride barberic, and female value as akin to property. I know I do. But nevertheless, men want to feel good about themselves, and women want to feel prized. Islam merely entices men to feel greedy without guilt and violent without remorse. It allows women to be passive and powerless cattle, but without shame.
