In this day and age, we learn to fight for ourselves and stand on our own two feet. Having somebody else fight for our cause is not very civilised. It also reflects on you maturity or imaturity
In this instance being cilivised means to discuss whatever it is you disagree with on your own.
Being uncivilised would be getting somebody else to do it for you. Like you havent grown enough to stand on your own two feet.
1. Bring (a place or people) to a stage of social, cultural, and moral development considered to be more advanced: "a civilized society".
2. Polite and well-mannered.
Hope this helps
