Since you have no dog in the discussion your point wanes. In a thread as this, the questions put forth in the article are designed to challenge the mormon to think. It provides an innoculant to others by causing them to think about mormonism outside of the box the missionaries may seek to place them within.
Now for yourself - a deeply held agnostic - this thread isn't directed to you and your agnosticism. So it isn't surprising to see your take on this - other than to question the methods. FWIW, there are a number here who've seen the replies numerous times and have left mormonism as a result.
But then that is just me.
Ok, let’s review.
1. The observation of an outsider with “no dog in the fight” is less relevant than the fiercely held biases of the opinionated.
2. Keeping people from learning about mormonism from mormons is preferable. Precisely how you would like others to learn about your faith, or professional skills, or political views, etc., I presume.
3. Protecting agnostics from the danger of mormonism is less important than protecting anyone else from the same.
4. You are taking credit for people making highly personal decisions about their faith. On the internet.
How about answering the question about jesus being taken from the earth? If god really wanted everyone to be christian he would have left jesus all resurrected and immortal on the earth forever and ever. [Naturally, I don’t really want an answer from you. This question is purely in satisfaction of my urge to ask something that I think is clever.]
