Well, we stop the discussion when everyone has stated their opinion.
Where we stop:
NTs would start arguing who holds the absolute truth.
NFs would start a smiley war.
SPs change the topic or starts trolling.
We are the only people the behave.
And no, I rarely visit them other boards. Over-the-top social ENFPs drive me away from NF boards, ESxPs drive me from SP forums, and NT-techno babble makes me bored.
