In my OPINION, this thread is interesting when folks share information/facts that others may have missed. When it comes down to opinions alone on hot button issues, we each have our own, and won't change them because someone else voices a differing opinion, any more than we'd switch teams to support because someone else likes the Jayhawks.
But we can learn things about issues if folks focus more on facts and less on opinions. At least, that is my opinion.
