People are Idiots

I'm about ready to give up on this abortion debate. I don't think the other students are even reading my responses or those of others. They just keep using the exact same arguments to try and justify abortion: "If you make abortion illegal, people will find ways to do it;" "It's the woman's body! She can decide what to do with it;" "Why should a rape victim be forced to carry a reminder of her experience for 9 months?" Really, are these people capable of free, conscious thought, or are they just listening to some barely audible moonbat waves that only pro-choice people can hear? The only people who are actually challenging my position are the professor and one T.A. The T.A. tried to say that a plane makes up for man's inability to fly, while contraceptives make up for man's inability to have "safe sex." Now, it seems to me that people can't fly without planes (at least not for very long), but they can still have sex without contraceptives. Just because you decrease the risk doesn't make it okay. Also, he says that contraceptives and planes are both ways of challenging nature, but that's not my point. Sex is designed to reproduce, and planes are designed to fly. No matter what you add or take away, they are still designed for the same thing. I'm about ready to give up on this, because the other students aren't listening and the professor is just arguing in circles. Any suggestions?
