My mind has been changed through discussions/debate. One issue would be legalizing marijuana for medicinal use. I use to be against it, but now I am for it . Another issue is the death penalty. Listening to what one guy said, I gained a new perspective & changed my mind. On here, Econgrad made a good point about eternal salvation that I thought about for a long time.
I enjoy debate because it reveals how people think and brings new points to light. Of course it can get out of control and become a battle of having the last word. But I think if we kick all those people off, it will get better. Haha! ( I'm totally kidding.)
