Answer:
Some people simply grew up with different beliefs and moral values than others. I disagree with my best friend on whether abortion should be legal. She believes that murdering an unborn fetus is wrong, while I believe that a woman should have the right to choose if whether or not a child deserves the life she can give it. I also disagree with my mom on how I believe I should raise my children. She believes that spanking my children will result in good behavior, I think it will scar them and make them not trust me. It's all in how your brain is hardwired.
