OP, just a suggestion to keep your messages on track and silence the idiots.

When you get a stupid question or a response that is just an outpouring of ugly vilification, just "beep" them.

Like the question about rainfall in the Amazon basin, or any post by the troll with the banana logo.

Just copy their post, reply "BEEP", and move on. We, the people who are really interested in what you have to say, will understand, and cheer you on.
