Unless science ever gets to the point that it can answer every single question in the universe, humans are going to turn to philosophy, spirituality and religion to answer the deeper questions about our existence, so I really don't think that wiping out religion is possible. That's in large part due to the fact that you can't control what people think, feel or truly believe in their minds and hearts.
Even if we could wipe out religion, we shouldn't, especially in America. It's a fundamental cornerstone of this nation's founding principles that everyone has the right to practice the religion they choose.
It's also quite prejudicial to hold Islam accountable for the acts of terrorists. Most followers of Islam follow more moderate teachings of peace and love, or at least tolerance. Many Muslim scholars point out that ISIS and the Paris attackers follow a belief system that is very inconsistent with the teachings of the Quran. ISIS is not so much a religious sect as it is a suicidal social phenomenon.
In the end, blaming religion for the attacks in Paris and elsewhere is a waste of time. First, it plays right into the agenda of ISIS, which is to spread hate and fear. Second, humanity constantly finds reasons to wage war on murder on one another in addition to religion, so violence would still occur, even in an atheist world.
