I don't believe wild claims that someone is a prophet because they say they, this is going against the word of God, there is a criteria God gives us.
I understand it is very difficult to look at Joseph Smith and look for the good fruit in his life. Looking at his life and works it fails to meet biblecal standards.
		
		
	 
That depends on which side of the story you believe, a little history for you.
 There was a man named Doctor Philastus Hurlbut, Doctor was his given name not his title, his mother had great hope for him. The Hurlbut family many years before had some sort of run in with the Smith family over a horse. The Smiths won the court battle but Hurlbuts kept the grudge. Philastus went to Ohio and joins the Mormon Church. Joseph welcomed him into his home and made him an Elder in the Church. Philastus repaid this kindness by committing fornication with a young girl in the neighborhood, no one knows who. He was excommunicated not once but twice because he would not repent. His whole purpose on going there was to find something to expose Joseph for a fraud, he found nothing. So he went to Joseph's boyhood home to dig up the dirt. He paid people money to give him juicy stories. These are called the Hurlbut affidavits and they are filled with all kinds of similar sounding stories; the Smiths were a lazy do nothing bunch of people who did nothing but dig for gold. A great deal of what people think they know about Joseph Smith and his family are built on those stories which were placed in the first anti Mormon book called Mormonism Unveiled. Hurlbut's reputation for womanizing was so bad that it had to be printed under another man's name E.D Howe. It's this book which first brings up the Spaulding manuscript accusations.    
Now I've visited their farm in Palmyra New York, it is a beautiful place. I found this at the website called  fairmormon;
"...To create their farm, for instance, the Smiths moved many tons of rock and cut down about six thousand trees, a large percentage of which were one hundred feet or more in height and from four to six feet in diameter. Then they fenced their property, which required cutting at least six or seven thousand ten-foot rails. They did an enormous amount of work before they were able even to begin actual daily farming. (each of those trees had stumps that had to be dug out of the ground also)
Furthermore, in order to pay for their farm, the Smiths were obliged to hire themselves out as day laborers. Throughout the surrounding area, they dug and rocked up wells and cisterns, mowed, harvested, made cider and barrels and chairs and brooms and baskets, taught school, dug for salt, worked as carpenters and domestics, built stone walls and fireplaces, flailed grain, cut and sold cordwood, carted, washed clothes, sold garden produce, painted chairs and oil-cloth coverings, butchered, dug coal, and hauled stone. And, along the way, they produced between one thousand and seven thousand pounds of maple sugar annually. "Laziness" and "indolence" are difficult to detect in the Smith family" Peterson 
Their farm on the tax roles was worth 71% more than the most of the farms in the area. So we can see that the affidavits are nothing but lies. 
There is another quote from a neighbor which you will not find in anti Mormon sources 
"Former neighbor Orlando Saunders recalled that: "They were the best family in the neighborhood in case of sickness; one was at my house nearly all the time when my father died....[The Smiths] were very good people. Young Joe (as we called him then), has worked for me, and he was a good worker; they all were. . . . He was always a gentleman when about my place."

There is another book written by John C. Bennett called 
History of the Saints is also a sources for much of the false stories about Joseph. Bennett was mayor of Nauvoo and a counselor in the First Presidency, I mean a very close friend to Joseph. Then one day he was caught committing adultery with Sarah Pratt the wife of Apostle Orson Pratt, so he was excommunicated. When Orson came home from his mission his wife and Sarah filled him with all kinds of stories about the Joseph and Orson stepped out of the Church. 
Now think about that Joseph Smith had started practicing plural marriage yet he excommunicates his next in command for adultery, now does that make since? It does if you realize Joseph did not consider plural marriage adultery. 
When the Holy Spirit leaves a person the devil rushes in and that's what happened to Bennett. It was he that accused Joseph of treason with the attempt on Gov Boggs life, prostitution and adultery. He egged on the attempts by Missouri to extradite Joseph back to stand trial, (this is an important time in American history of law because it establish some of the legal rules when it comes to a writ of habeas corpus) In his later life Bennett got caught selling diplomas and had many accusations of adultery. His book is also full of lies and distortions, he has a whole chapter on Sarah Pratt and how Joseph tried to seduce her when it was the other way around. However Orson began to get the other side from different people and came to the conclusion that his wife and Bennett were at fault. He returned to the Church and retained his apostleship. He never divorced Sarah and he continued to support her financially but they never lived as husband and wife again. (at least that's my understanding, she was a very bitter woman)    
Another book written much later is No One Knows My History by Fawn Brodie. She uses some of the stories or at least the concepts of the other to books to build her story. She has Joseph jumping in and out of bed with every woman that walked passed him. She gives a list of children who she claimed be long to Joseph but 70 years later with the science of DNA they can't find a single one.  
My point is that much of what you think is the history of Joseph Smith is based on accusations written by men who were adulterers themselves and trying to cover their own sins by accusing Joseph. 
At the time of Joseph Smith and up into the early 1900s there was no rules to writing history, historians just wrote to fit their own perceptions and agendas. Much of it is just propaganda and we all need to learn how to read through that to find the truth.  Today's historians have to have indexes full of notes and references. My only problem with some of today's historians even Mormon ones is they give equal weight to every crackpot out there. I get tried of "could be" and "maybe" while trying to read the minds of long dead people.
