Prime example from this dumb book:

Page 10 claims: (Jabez) prayed, "Bless me, and enlarge my territory. Let your hand be with me, and keep me from harm so I will be free from pain." What should we assume about a man who uses the words "me" and "my" four times in two sentences? - He uses this as an example of a "selfish prayer" based on his use of those 2 words.

The very next page he uses Psalm 139:23-24 as an "unselfish prayer" example. "Search ME, O God, and know MY heart; test ME and know MY anxious thoughts. See if there is any offensive way in ME, and lead ME in the way everlasting." - How about 6 times in 2 sentences? According to your last example, this is even MORE selfish.

Anybody who bases the selfishness/self-centerdness of a sentence on the use of the words me/my/I loses all credibility with me.
