It is not even about that.
People are basing their conjectures on superficial results.
People are getting the wrong impression of what the aura is.
Used to all that generic telekinetic crap from a million other series, they are wrongfully thinking that this power is some sort of mind power which is similar to abilities like moving things with your mind or remote viewing.
This couldn't be further from the truth.
The Aura is not even remotely connected to the Psychic world.
It is about the pure will of a person being so powerful that it overwhelms other people with weak resolve.
When you are being stalked by a rapist, do you not feel a murderous intent?
When you are watching a dramatic film, do you not feel emotional from the actor's actions?
It is the exact same thing here but merely amplified by typical "shonenity"
The pure feelings of a person are so strong that other people can actually feel them. Naturally, one does not have to be aware of the other person.
After all, when one is suddenly being stalked, does he not feel something is off all of a sudden.
It is simply a case of this feeling being so strong that the person cannot handle all that will power. It makes pure sense from a neutral point of view (considering Shonen Law) and is not even remotely connected to psychics.
Think Tiger Woods, Whenever he plays everyone else on average does a stroke worse then normal.
