I think most of these comments are understating the emotions involved. Some very significant portions of many populations have strong emotional ties to their Gods, or their science. It isn't difficult to show some imperfections in every religion I am familiar with, but remember that science gets things wrong too. Anyone who wants to see either one as fundamentally flawed has more than adequate material to reach their desired conclusion.
Even if you manage to demonstrate that evolution makes Gods unnecessary, you would still have to show Gods don't exist to actually destroy religion. You are also going to have to teach advanced science to the masses before they understand why it contradicts their religion. Many people are experts in neither and see science and religion as compatible.
