One of the first things I noticed about atheists when I began my apologetics career is that a lot of them tend to have a fascination with psychology. They love to try to discredit you by trying to explain why they think you're a Christian. Your parents were Christians, you've suffered a loss, you're scared of death, you're white, etc. If there is anything about you that an atheist can use to explain where he thinks you got your Christian beliefs from, it's very likely they will attack that.
This is called the genetic fallacy. Attacking a belief based on its perceived origins isn't a valid argument. Truth, by definition, exists outside the mind. Therefore, no matter how many reasons an atheist might be able to give for why you, specifically, are a Christian, that still doesn't make a scratch on Christianity itself. For example, yes, my mother is a Christian, I have suffered loss, and I am white. But even if I was an Arabian who was raised Muslim and never experienced anything worse than a grazed knee, that wouldn't affect whether or not my view is correct.
If Christianity is true, nothing about me would make it any less so. I could even cease to exist, Christianity would be just as true as it was the day Jesus walked out of that tomb. On the flip side, if Christianity was not true, my own personal traits would still be irrelevant. The atheist should be able to prove his case without any appeal to my psychology.
As it stands, Christianity is true, and atheists have a very hard time proving otherwise. This is why the majority of their arguments are so fallacious that an amateur can shred them. Psychological arguments like the above are an excellent example. If Christianity was false, you could bring valid arguments against it, yet atheists all too often need to argue from the psychology of their opponents. This indicates that not only is Christianity a strong religion, but that atheists actually know it.
