They bully people using social media and web sites. Ironically, their main approach finds them using anonymous twitter accounts and websites to bring about their desired action, usually "repentance" of their targets.
Pastor Guthrie goes on to call for action:
Good men must rise and say enough is enough! James White, JD Hall, and their thugs must be told ENOUGH! Ministry is not about attacking other ministers. Dr. Al Mohler, Dr. John Macarthur, and leaders of the every group of Pastors involved can and should speak with one loud and strong voice and say NO MORE! It is not enough to distance oneself from these workers of evil. They must be repudiated!
Take the time to read Guthrie's entire piece. You will not regret it I assure.
