Aussi vs. non plus

Question

In the sentence " I also don't like some soccer fans " I used "je n'aime pas aussi" but the correction said it is "je n’aime pas non plus"

What is the reasoning here? When I read the grammar lesson behind it, it says "non plus" is more like "not...either" which is definitely not the same meaning as also in English.

Accepted Answer

Aussi is used in positive, affirmative statements. 
 Non plus is used in negative statements, to carry equivalent meaning, being able to be translated in English as ‘also’ as in the sentence noted.
