In response:
Yes, the Mormons most definitely ARE doing "warning" work, and do believe the return of Jesus Christ to be very near. It would take one JW more than 50 years of "service work" to equal the hours spent by just ONE full-time missionary, so please don't bother to say Mormons "merely" serve for two years.
Mormon missionaries make good use of their time and then return home to college, marriage, job, family, and ongoing Church service beyond what any of my JW family members could imagine doing. And Mormons don't just sit around having meetings either. They are out in the community doing some real good, at homeless shelters, Habitat for Humanity, food banks, and other unpaid charity work for the benefit and blessing of others.
As for the Book of Mormon, you reveal a low and uneducated mind when you slander someone else's scriptures. If you don't care to respect the book, then don't. Not everyone does. But those people with class keep their negative opinions to themselves or at least frame them in kinder terms, as Cygnus did.
And finally, your family is most likely NOT doing "baptisms for the dead" every Saturday night. I suggest you have further conversations with them so that you won't continue to sound so abysmally ignorant. There is much more done in the Temple than that. Again, you reveal a total lack of class.
If all you can do is throw stones at others, how can you hope to attract anyone to your religion?
