To answer marm's question, yes you can pretty easily get to know what the types are like online. But being trollbait isn't a great way of doing that. The way I see most of these conflicts go, is that type 4 NFP will get offended at something the ENTP says. So they go aggro on the person. ANYONE will get defensive when someone gets aggressive with them... so what does the ENTP do? Sure they get defensive, but their idea of being defensive, especially over the internet, is to steamroll someone with their mind. Thus, conflict. I think that the main point that the ENTPs have been trying to get across to these people is just to engage them on an equal level. Logically analyzing and being fair, not being personally offensive and vengeful. That confuses them. This is just from observing, lol.
AND THEN THE THREAD DIED.
EDIT: Amargith is a 4! Not a 9. She just wants threads to actually go somewhere, it's not a reason out of keeping the peace. Trust me, I've talked to her enough to know she's 4.
