Yes that typically does happen. And one person gets attacked from all sides
or one person is attacking everyone else.
Too much emotionalism...but why I do not understand.
If a person is so convinced they have the absolute truth, an airtight system of theology based on the word of God, it should stand up well to questioning.
In my experience, in my line of work the most assured confident person with a good grasp of the facts is the person who does not need or use ad hominem attacks.
