Why forgive? There was no slight given...unless you take offense at the insinuation that protestants know little of scripture. Of course, doing that would be no different than us Catholics finding the initial article of this thread insulting.
"Again, a demonstration of a protestant being ignorant... "
That critical statement was directed at an individual. You can sling all the arrows you want against Presbyterians, Protestants, Microsoft, baby kittens, whatever group you want.
But the rules on the FR religion forum forbid you from making personally insulting comments to another poster. Which you did.
If you want, we can ping the RM for clarification. I generally prefer to permit a poster to either apologize or retract the statement. Either way, like all rude and careless remarks, it reflects poorly on the one who makes it.
