With all due respect, good doctor, I think you need to read the thread again. There is no prohibition against introducing any theological issue.
Here's a hypothetical I think is pertinent.
Some people consider Wiccan to be a religion; even the U.S. Army makes allowance for it. What if a Wiccan fervently insists their religion is Christian?
What is the permissible response on Free Republic from an orthodox Christian, i.e. a Presbyterian, a Lutheran, a Roman Catholic?
Because it's understandable that most traditional/orthodox Christians would be appalled by that error and naturally want to refute it. I'd expect a Jew to challenge me if I said I was "a Jew who believed in the Trinity and Christ's resurrection."
Most democrats and Republicans do not fear for their mortal soul if ignorant musings are offered about politics in their presence.
But "Defending the Faith" has been a rallying cry to the death for the past 2,000 - 5,000 years. All jokes aside, it's no small matter to people of faith.
So? If a Wiccan says they're a Christian on this public forum, where lurkers and children and shut-ins and DU get all their information, is it okay to rebut that claim?
Partisanship, after all, is not a bad thing. William Wallace never actually yelled "Freedom!" as he lay dying.
He shouted "Scotland!"
