I'm not sure I'm in, but anyone who sends that letter will need to correct the grammar and mostly spelling. If you want them to listen to you, you need to sound professional and like you mean business. They aren't going to listen to you if you're misspelling words, using capitals in the wrong places, and other incorrect grammar.
Sorry but what I'm saying is true, and I'm only trying to help you. I'm really sorry if I sound harsh but this is what you have to do if you really want them to change.
(BTW I really agree that most of those things don't belong on AP. Especially "Monsters Inside Me" and "Pit Boss." These things are in no way focusing on animals and need to be moved to a different channel. Maybe AP needs to create a sub-channel for those shows if they don't want to get rid of them, but they need to get them off AP.)
