Its impossible to cleanse arguing fully. As Mutual said, "There are many age groups" and there will aways be conflicting ideas. Unless you want everyone to submit to each others idea and not stand up for what they think is just.
See you didn't put much though into your response because you are one of the people who like to voice their opinion. With that being said if you like to voice you opinion and the more often you do so people will dislike what you have to say and then they will tell you.
As I stated above the only way to get rid of arguing would be that everyone has to submit to one another and that just ain't going to happen.
