"most can also see the trends of those with their own agenda."

Hahaha - except I suspect you wrote that with a straight face.

Is there anyone here who most saw as having their own agenda and vilified them? And then were proven spectacularly wrong?

I'm not convinced "most" are a reliable indicator of "own agendas". I prefer the yardstick of reason and logic - not mass hysteria, but each to his own.
