I didn't back up what? The reason why I don't post my ideas on these threads? To restate: "I have my own ideas but, just like everyone else, since no one was around, it's all theories/speculation." That is and was my opinion; there's nothing to back up.
As to why I don't post my specific ideas on these threads, you have already proven my point (and, backed them up with your own behavior): You are representative of the numerous obnoxious posters on these threads. The condescending remarks are not even limited to those who express their ideas, you direct nasty comments to those who won't state their specific ideas.
No scholarly person would define debating as belittling, demeaning others, arguing for the sake of arguing, and/or name-calling. As there are very, very few who attempt to do otherwise, and keep it to some kind of intelligent high ground, it's nothing more than an exercise in futility. Generally, the mob mentality takes over in these threads. Unfortunately, your posts are the general rule rather than the exception.
