GMIL readded my dad on FB after I had asked her to delete him

I don’t think it is enough that you try to explain to her why she should delete him. I think you would have a better understanding of this woman if you ask her why she wants to be friends with and associate herself with this type of man, and put her great-grandchild at risk of this monster. Her answer to that will give you a lot of information about what she is capable of. It could be that she is very misguided and believes family is family no matter what, or it could be that she is just trying to one-up you because she feels like you are making her her a DTAP vaccine. If it’s about the vaccine, then this problem may solve itself as soon as your father gives her any trouble. If it’s about family, that may be a more dangerous situation since she may have this idea in her head that she is “helping” this poor man feel better.
