The practice of Islam is filling a vacuum left when around the beginning of the 20th Century, the world began leaving their trust and faith in the God and Father of Jesus Christ.
Ironically, it is actually the dogma of the pseudo-intellectuals in society that is the most vulnerable to critical thought, and this scrutiny is what needs to happen. Political correctness is just one element of an extensive philosophical construct that has been perpetuated in Western society as ‘modern’ and ‘progressive’. IMHO, we should be moving forward, and our understanding of the world growing from generation to generation, but the way to do this is not by suppressing conversation and individual thought, and not by propagating a specific way of thinking such as that which is ubiquitous on almost every college campus.
To me, God is truth, and to be a truth seeker is the highest order of intellectual activity. Further, fervent secularism is also a ‘belief’ system, and requires a lot of blind faith. To stop the slide away from spirituality of which you write, IMHO we need to fight back against the false characterizations of spiritual thought and faith as anti-modern and anti-intellectual. Nothing could be further from the truth.
