Dude: You know, Obama voted present 29 times on pro-choice issues. Sounds like he's not really pro-choice.
Me: Actually, in Illinois Senate, "present" means "no". Planned parenthood asked democratic senators to vote "present" to kill some very rotten anti-abortion bills to support Illinois senators in problem districts. By voting "present", the bill could be defeated without the pro-choice senators facing election issues back in their area. He explained that after the Clinton's misrepresented his votes.
Dude: If Obama didn't want people misrepresenting his record on voting "present" issues, he should have explained himself before other people started making accusations. Then he wouldn't have to explain it to people.
Me: I never thought of it that way.
Dude: I didn't think so.
Me: By the way, your Mom's a big whore.
Dude: What? She is not!
Me: Well, you should have explained that before I started making accusations. Then you wouldn't have to explain how your mom isn't really a big slut who does everybody.
Dude: You're a jerk.
Me: Yeah. I've heard that. Usually from people who make stupid statements.
