Yes, I have thought about it. It's because on some topics, Terri Schiavo being one of them, many people lose all sense of logic and reason. It really irks me to see otherwise smart, capable people talking nonsense.
That's why I avoided 98% of the Schiavo threads back in the day. I'm not even here to discuss Schiavo, really. I clicked on the thread because I was actually interested in the medical advances (and to see if it fit my ping list, to be exact).
