The patent isn't about editing messages, it's about the user interface/look and feel/gestures used to edit messages. It's clear if you actually read the claims in the patent.
This narrow examination of the claims goes to the heart of how broken the current patent system is. Anyone can look at this and see that there is zero innovation here. These patent claims here are just as flimsy as those of the patent trolls who attempt to sue Apple. Seriously, I read the patent application and just shake my head, thinking is this a joke? People take this seriously and award it???
