Answer:
Agree about the issue or be against it and discuss.
Step-by-step explanation:
When writing down an argumentative writing, you may write down as many current issues that you can think of, even if you have not yet formed strong opinions about them. Just make sure that they are issues--matters open to discussion and debate. Arguments are not one-sided, as much as we might sometimes wish they were. If they were only made up of one side, it would be so much easier to win. But such is life, and facing different perspectives from your own is a part of an argument; even if you feel other perspectives are harmful and perpetuate hateful ideals that you cannot even try to understand on a personal level.
You can hope that everyone will come to see things the way you do, but until then, give them a hard time by proving that yo have got the knowledge to back yourself up and rid them of any leverage they might have been prepared to place on your assumed ignorance.
