I suppose you are referring to the forum?
the biggest attacks I see are topics where there seem to be scriptures that support both sides. People have their views pretty entrenched about certain subjects and before you know it, anyone who disagrees or shows a group of Scriptures that seem to say something different, then someone is labeled a heretic.
I will staunchly speak out about something that completely contradicts the Bible. For instance if someone says adultery is ok, I will adamantly stand against it, because there are no scriptures that would even hint at supporting it.
However, I am always amazed at the amount of anger shown towards other Christians who have different views on free will, predestination, healing, etc where we see a multitude of scriptures sometimes showing different things.
