I have never really understood why a minor 2nd is only a semitone apart and yet a natural minor scale or dorian scale ect. are a whole tone apart ?

The word "minor" has two meanings.

1. For intervals: Some intervals (second, third, sixth, and seventh) have a choice of two notes. The lower choice is called "minor" and the higher choice is called "major". 

2. For scales: a "minor scale" is referring specifically to the quality of the third.  So if the scale contains a minor third, it's a minor scale.  If the scale contains a major third, it's a major scale.  All regardless of all the other notes in that scale.

So, with your example of a natual minor scale:

The notes of C natural minor are: C D Eb F G Ab Bb C

The intervals are:
D : major second
Eb: minor third
F: perfect fourth
G: perfect fifth
Ab: minor sixth
Bb: minor seventh
