INTJs? Scary? Naw, they're just a bunch of big softies...
^ All right, just joking, just joking.
I can see why some people are scared. Sometimes when somebody posts a thread with an idea, an INTJ or INTP may simply discredit a person for one mistake they may have in their post and point it out quite bluntly. However, I know that most of you guys around here don't do that; this is simply what I noticed
can happen on occasion.

Or perhaps I'm getting this mixed up with certain experiences with my INTP brother.

Eh, well, forget it then.
However, once a person really get to know you guys, they'll find out that you're a bunch of nice, actually easy to approach (and sometimes read!) people. ^_^
