The people of america do not vote for the president senators supreme court justices

The correct option is:"Supreme Court justices"

The Supreme Court of Justice of the United States of America, also called the Supreme Court of Justice of the United States, is the highest court in the United States of America. As such, the Court is the head of the Judicial Power of the United States.

The Court is composed of a president (Chief Justice) and eight associate judges (Associate Justices), who are appointed by the president of the United States and confirmed by the "advice and consent" of the United States Senate. The appointed judges of the court serve for life and can only be removed by Congress through a process of impeachment. Judges may resign from their office of their own volition. No judge has been removed from office, although many have withdrawn or resigned.

well it depends i think people around the world are coming around to gay marriage. but if you are talking abortion then wow, so much to talk about. such as men thinking they have the right to choose if women can, the fact there are health concerns if the women can't get one, and many more arguments to discuss. so i would definitely say abortion would be a much more interesting topic.
