Let's discuss Mormonism.

So the branches would be:

Catholic
Orthodox
Protestant
Mormon?

Rather than Mormon, I'd make that fourth branch (if one restricts Christianity to just four branches) be Restorationist, which would include also Adventists, Jehovah's Witnesses, and other similar groups that hold that they are restoring lost practices of the early church.

So they'll have to change the books then, because the books say all Christians are, Catholic, Eastern Orthodox, or Protestant.

Well that's just not so.

Well, for a while there the Protestants denied that the Restorationists were Christian and the Catholic and the Orthodox saw nothing to distinguish Restorationists from Protestants.

Okay, thanks.

Also, why is it mainly men that do missionary work? (Also, is it a requirement, I know very little about Mormonism).

The age at which men may go on missionary work is lower than that for women.  So while for men it was something that could be done between high school and college, for women it generally needed to be done after college, if at all. (Just recently the the women's age has been lowered, but it will still be higher than men.)

Being sent to Scotland is how my former Mormon friend met his boyfriend

Any reason he's no longer a friend?

How can drinking alcohol be considered reprehensible or even sinful? After all, Jesus drank wine and nowhere does the Bible condemn moderate consumption of alcohol.

Can't speak as to Mormon doctrine, but I get a fairly healthy dose of Adventist doctrine on the subject from a radio station I listen to. (I don't always agree with them, but their station often has the most tolerable stuff to listen to while I am in the car.) They point out that the Greek word for wine also encompassed grape juice, much as the word cider in the English language includes both soft cider and hard cider.  So they insist that Jesus drank unfermented grape juice.  Their arguments that he must have rather than he could have seem to be based more on arguments that he would not have had anything to do with destructive alcohol than a specific scriptural basis.

By the way, I'm going on my LDS mission in a little more than a month, so if you have any more questions about Mormonism, ask before then.

So where are you headed, or do you not know that yet?

Kenya?

That might cause Bushie to consider becoming a Mormon by adding a letter.

Do you (Zioneer or anyone else) see the Mormons no longer consider themselves to be Christians within recent years like the Unitarians did?

Doubtful.  While they do believe in some additional texts as scripture, they still give a preeminent role to Christ in them.
