The 7th function is weak unless we're using it aggressively... so this means that ISxps have a Se temper. Thinking about this... it makes sense. I don't generally allow myself to get angry anymore, but when I did I'd often throw things (mostly furniture) or break things (usually nothing important). I also used to go crazy on the heavy bag when I got mad.
In theory, ISFps have weak Fi and a Se temper. This sounds like a dangerous combination. I feel violent impulses when I get really mad, but NEVER to the extent of physically hurting someone. I have in the past said really mean things that I KNEW would deeply hurt them, but that's not really Se, is it?
lol perhaps this is why I don't allow myself to get angry anymore
