For the record, it is a good thing when people move beyond the stage of calling each other names. For many, it is a stage that ends during middle school. However, it is not to late to start now. In addition, you could try putting together a coherent argument. Give it a try, here is what you do:
Make your statement
Back it up with evidence, linking back to why your evidence proves your point
Conclude with a reiteration of your statement.
Have a terrific day.
