topics for essays

So Prof. Sweeney told us that we as a class had to chose 3 topic to write about.I was thinking that he was just going to give us the topic but no he wanted us to choose.But how were we going to do that if everybody is not going to agree on the same topic.There would always be at least one person who would not agree with everyone else which was so frustrating.So what we did was we tried to convince that one person who didn't agree and let them see why we should write about it.But we also had to compromise,like we would have to give up something.I guess the whole point of us choosing our own topics was for us to hear each other out and compromising with each other.This took us 2 class days to finally pick 3 topics to write about.Never again!!
