I'm doing a debate on being against abortion. What are some zinger and high points for that debate to give to the class?
I would try to appeal to the "life starts at conception" point. Yes, I know that fertilized egg doesn't look like a real human being yet. But left alone, that fertilized egg will replicate over and over, after three weeks, it is large enough to be called an embryo, after eight weeks, a fetus. Let it go all the way to forty weeks, which is full term, and out comes a fully developed human baby. How can you not say life starts at conception?
I think the best example of a zinger would be appealing to a person's emotions using facts. You can describe in the detail how an abortion is performed. That usually grosses people out, and it is hard to argue against it.
I am not big on "zingers" when you should be dealing with facts. However, it is a good idea to provide something that visually impacts your audience. I would suggest the referenced video below. It is pretty difficult to deny the life value of a fetus with this in front of you. It should provide a good starting point for your fact finding.
