>Still not seeing the issue. If I have Twitted them, I do NOT want to talk with them. It's not my responsibility to worry about how someone handles it.

Well, I would not want to hurt someone on purpose even if I dislike this person.

You have no idea how someone may handle such things. What if you drove this person to do something bad either to you or to the person himself? Drove the person to suicide, for example?

Will you still say afterwords it was not my responsibility?
