"And the man that committeth adultery with another man's wife, even he that committeth adultery with his neighbor's wife, the adulterer and the adulteress shall surely be put to death." - Leviticus 20:10
3. The Sermonator
A close relative to the Self-Promoter, the Sermonator trolls various comment forums to find some way to divert the conversation to his favorite subject -- most often something related to morals, religion or a particular political view. No discussion is too interesting and no community too engaged for the Sermonator to subvert into a tedious homily on his topic of choice.
