Although I certainly agree with you here, it's very hard for a non-believer to really find things that are genuinely good and positive. All he can do is imagine what things might be positive about being a Christian. Let's take prayer, for example. He might understand that people find comfort and solace in prayer. On the other hand, he will feel it's a terrible waste of time, because they will avail nothing.
But as you mentioned, bashing is something entirely different, and I agree.
