It depends on what you think being a Christian means. To us it means that we believe in Christ. We do not worship Joseph Smith, nor do we seek to worship anyone else except the true and living God and His son Jesus Christ. You have no proof that Mormons aren’t Christian. In fact, the Book of Mormon overwhelmingly mentions Christ and his workings and wonders in the Americas. We have always believed in the Bible, the King James
Version anyway, as well as the Book of Mormon. Like you said, “Study it for yourself.” Only then will you be able to come to a full knowledge of our beliefs.
