Have you ever met someone who had a strong opinion about a controversial topic? For instance, someone might believe in reincarnation, a woman's right to abortion for any reason, the need for reparations for descendants of American slaves, freedom of speech, the legitimacy of socialism/communism, the need for unity among Christian denominations, illegal immigration, the right to free healthcare, medical benefits, and food assistance, perverse views about human sexuality, that evolution is the best explanation for how we got here, the right to defend your family with a deadly weapon, how to raise a family, or who is the best college football team. All of these ideas have been expressed by different people at different times, but are they right?
