I don't see the definitions defined above as too different. They both detail behaviour likely to cause arguments. There are those on here that do just that and it has more to do with their attitude than what they are saying. Talking down to people, insulting their intelligence or laying traps for them is just dishonest trolling in my book and I will no longer interact with these people. Whether they believe what they say or not is irrelevant. I recommend everyone just ignores those who annoy them. It is very liberating :-)
