Forcing others to consider your beliefs in a setting where they were not invited and should not be expected may not be the root of all evil, but no-one is claiming as much. That logic still doesn't mean it's an appropriate (or right) thing to do.
Personally, I think it's great that Jason overcame depression and if he believes God helped him do this then great.
But however well-meaning it might seem to the sender, Jason doesn't know who he's sending these things out to. He cannot know the effect it'll have. Some people may find it genuinely distressing for reasons you have no right to contemplate. Personally, I believe that animals shouldn't suffer but that doesn't mean I'm going to use this forum to graphically list out the kinds of animal cruelty that take place every day. I wouldn't just tell you not to read it. I'd take responsibility at source.
By doing so I respect your right to only expect that in a setting where it's relevant or related. This is the flip side of the argument that makes those saying "Jason can do what he wants with his software" are, whether they like being called it or not, 100% intolerant of.
