Do you have the right to be an atheist?

So to respond to your response about #3.  Something that is supernatural is something that is beyond scientific understanding or beyond the natural laws.  Supernatural is not what is beyond current understanding.  However using the scientific understanding notion of supernatural is a poor one at best.  For example we have inner qualia, like what the color yellow looks like to use.  These inner qualia actually do have the potential to be beyond scientific understanding.  They do not however seem to have the potential to undermine the natural laws.  Superior is a relative term.  I am for all intents and purposes superior in functioning than some human beings.  I am not, no matter how much I want to believe it, the god of imbeciles.

But either definition you use, teleportation is not considered supernatural.  We actually have theoretical ideas about how we would do it too.

A quick google search of the definition of Supernatural got me this:

attributed to some force beyond scientific understanding or the laws of nature.

So according to me,to classify an occurence as a supernatural occurence it should be
*Beyond the scientific understanding

And i completely agree with this.
You said that teleportation is a completely natural phenomenon as we have theoretical evidence that suggests the possibility of teleportation.

I think this statement of your's is faulty, 
The theoretical aspect of teleportation is completely natural to us.
The practical aspect of teleportation is supernatural to us.

BUT if a person/being were to randomly teleport across the street,of course we would not view it as supernatural(Because now we know that the practical implementation of a theoretical summary of teleportation IS possible).
Its tricky because we consider something as supernatural when we believe it will not happen holding the CURRENT scientific understanding as evidence.
So as long as someone doesn't randomly teleport across the street(Or they implement a practical implementation of the process),teleportation is supernatural but the moment this phenomenon actually does happen it is natural.
Thousands of years ago it was Supernatural for a person to instantly communicate with another person on the other end of the world.
Today it is not supernatural it is natural.
The labeling of something as Supernatural or natural depends upon our current scientific understanding.This is what i think.
Furthermore i didn't use teleportation in the sense that it is the ONLY phenomenon that would classify as supernatural.I used ideas like teleportation or invisibility because there are already theoretical proofs that they are possible.
I'd definetly sound like a lunatic if i said that something without theoretical proof is possible to others,that's why.
