Why do Christians always produces an atheist?

If you are talking about Christians kids that is not true, all my kids are believers. Raise up a child in the way that he should go and when he is old he will not depart from it. Atheist parents do tend to raise some fine christian kids. Madalyn Murray O'Hare is just one example. Her son is a preacher. :P

Not always. And what do you mean by choose an atheist?

Lols better than a hypocrite christian who gets judged more because hypocrite christian know more of God's laws=more punishment in the lake of fire.

So better to be a honest atheists than hypocrite christian, less punishment in the lake of fire.

There's always a clear thinker who wants no part of a bad idea.

If you mean why do Christians always become atheists, that is not a truth. Many do become atheists, though, because they keep their eyes on fallible man instead of Infallible God.

Everyone is born atheist. You have to be taught religion/belief.

The pencil, because vests having no sleeve.

Not understanding your question. Try re-wording it.

Not always.
