It is well known that many Jews (even rabbis), with shouting voices, flailing arms, argue vociferously with fellow Jews over the finer points of the religion. I don't think that many have argued for atheism, but the arguments have not weakened their religion. Quite the contrary, after Jews were sent to Nazi concentration camps, ordered not to practice their religion, starved, beaten, and raped, few abandoned their religion. In early Italy, Jews were forced to convert (called Conversos) to the Christian faith, but many had secretly maintained their Jewish roots.
My point is that argument about religion doesn't harm it, but strengthens it. It exposes our minds to all of the possibilities and we either convince others of our way of thinking or they convince us, or we agree to disagree. But the concepts are thoroughly considered, and that makes the religion concrete in our minds.
Science is not the enemy of religion. Scientists are not necessarily atheists.
Science can strengthen religion. For example, scientists say that the universe was created (with a big bang) 13.4 billion years ago, and theists say that God created it 6,000 years ago. Fossils, carbon dating, and other means seem to prove the older date. Yet, science also asserts that there is no absolute time. Special Relativity (of Einstein) says that fast objects slow time. General Relativity (also Einstein) says that strong gravitational fields slow time. Hence, science provides a means to make God have his own time and a means for us to have our time (and the times are not equal). Thus, science, at least on this point, doesn't disagree with religion (nor does it agree with it, necessarily).
