No. That's a red herring. There are numerous disagreements on interpretative issues but not on the basic and core gospel. I've been in multi-denominational bible studies with all Protestant and Catholic denominations represented.
These differences were enough for Christians to torture and kill each other over throughout Christian history.

And I've seen Protestants tell Catholics that they're going to hell because they're not following the Gospel and are not Christian. A large number of those of other denominations don't consider Mormons to be Christian. Face it, you can't tell another person he's not a Christian, because right now, somewhere, there's another Christian who'd tell you that you are not a Christian because you don't believe exactly as he does.
