This thread is beginning to annoy me, really badly.
Why are ESTP's intimidating? Just because they are straightforward?
And I don't think the issue you are talking about is type-related, you are analyzing everything from this perspective, even if it is non-related.
How can you know for sure that every mechanic in there is an ESTP? Did you test each and everyone of them? Or are you simply making stereotypical assumptions?
Don't get me wrong, what infuriates me is not the fact that you are talking about my type, but the fact that you are not looking at issues from a number of angles, but from a single point of view.
The answer to your question, to fit your stereotypical analyze, is no, we do not realize how "scary" we are. It is in our nature to act so, it is not deliberate.
