Not commenting on Elijah or that post, but when you say its strange some people notice other people don't, of course they do?
For instance, Romeo and Juliet. You can study Shakespeare all your life and have a degree in English Literature and still not know the meaning of Shakespeare's message. If you overlook who Roseline is, you have no idea who Romeo is or why he is so prone to "fall in love with the last girl he sees".
I didn't know that until someone pointed it out to me years ago, and they were not trying to outsmart anyone. They just had a genuine love for Shakespeare and why he wrote what he wrote. Not everyone is trying to get "one up" you know. Otherwise, what are teachers for if everyone knows everything already? You don't have to assume the worst in people in the first instance, that's all. Just sayin...
