This only covers comments, to bad it does not cover anti-religion threads that are only created to bash a certain religion and to illicit negative diologue. That gets a wink and a nod sometimes.
Christians who follow the Bible in its proclamation of the Gospel, according to the way we are told in those Scriptures, are duty bound to tell all the other false religions and those perpetrating false doctrines (those "doctrines of demons") that they are pushing cult teachings and that those teachings will lead straight to hell and to eternal torment in the lake of fire.
Christianity is "exclusive" in its teachings and all other religions are "false" and deserve to be called false and heretical. They deserve to be bashed out of existence for teaching doctrines that the Bible calls "doctrines of demons" which will lead to death and eternal separation from the God of Abraham, Isaac and Jacob.
I agree with your designation of the truth of the gospel. Regardless, we are told to “speak the truth in love”, so I still think the guidelines in the OP about posting comments are important to abide by. I cannot be responsible for how someone receives the message but I CAN be sure of my motives for posting and the tone in which I speak/write.
Paul would have been a bit MORE bold...
As for those agitators, I wish they would go the whole way and emasculate themselves!
