I do mind. If you look for a few years for "rational" arguments for Mormonism you will be wasting your life duplicating the effort of thousands of people before you. Please don't. Even if you remain Mormon, there are far better things you can do than theology.
What should I spend my next few years of rationalism doing then?
It seems that according to you, my options are
a) leave my religion in favor of rationalism. (feel free to tell me this, but if my parents find out about it they'll be worried and start telling me you're a satanic cult. I can handle it.)
b) leave rationalism in favor of religion. (not likely. I could leave Less Wrong if it's not open-minded enough, but I won't renounce rational thinking.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
