Funny you use Mother Teresa as an example, as her reputation was actually the result of positive editing
I think sometimes its just annoyance, but sometimes yes it is hate. And I'm not one of those "hates a strong word" folk. I don't think it's a particularly strong word. Abhor, detest, loath, maybe. Hates essentially been watered down to mean dislike, and I think its perfectly fair to feel that way about HMs.
