The lack of intellectual integrity of some Evangelical Protestants in their criticism of Joseph Smith

I recently had a brief exchange on facebook with Jen Johnson, a former Latter-day Saint who converted to Evangelical Protestantism, and another Evangelical on the question of whether it is proper to remember the death of the Prophet Joseph Smith as well as if it is proper to sing hymns such as "Praise to the Man" that lauds the life and accomplishments of the Prophet; one can find the exchange here. I do believe it shows the lack of intellectual integrity some (not all) Evangelicals have when it comes to discussing "Mormonism"; as for Johnson, she has a reputation of being grossly ill-informed about theology and the Bible, as well as the LDS Church--a well-deserved reputation if you ask me.
