Forgiveness is an excellent quality imo!
People react/respond to death in various ways. Even those who are Christians might not realize their responses are uncalled for (to the death of Tammy.)
There's no reason to denegrate someone who has passed and has no more affect upon the world.
She had many struggles; the only difference is the media showed hers to the whole world. Who can stand up to that?
Regarding taking down the post, have you further thought about that? Of course, you've forgiven all those people who posted mean-spirited things, but why deny the others of reading what you posted about Tammy? Just because they haven't forgiven her for any of her poor choices doesn't mean they don't have the 'right' to show their own ignorances.
You know Christ told the disciples, when they came to him about how they prevented someone who was not a disciple from preaching, that to let them be, that He would sift the wheat from the chaff and that if any good comes from one of them, that would counter the negative they gave.
I believe God used the Bakers in spite of themselves. Just like He uses me.
