I'm not mincing with words! I'm not going to dance around the fact that Mormonism is false with obtuse circumlocutions. Language should be clear and direct. If the word heresy is offensive then the truth is offensive.
I'm not offended by the fact that Mormons think I'm a heretic. I'm not offended by the fact that Muslims think I'm an infidel. I'm not offended by the fact that atheists think I'm deluded for believing in any type of a higher power.
Praise God that He found you. Now, as you are the Prodigal Son, surely you should know better. Had Christians gone out of their way to label you as a Wicked Damned Unrepentent Sinner Wallowing in Sin (as all atheists are) how likely would you have been to want to become a Christian?
The world hates righteousness, and when I was a part of the world I hated righteousness too.
