RE in the last several decades is not aimed to convert anyone. It is more about teaching different religions to teach you what other people believe as well as different viewpoints in controversial subjects. I remember that my RE included discussions on abortion, human rights, animal rights and marriage and their different viewpoints due to different religious beliefs. The fact that religion plays such a prominent role in shaping someones own personal morals, it is somewhat useful or important to understand how other people in society may view things differently to you and though religion is less prominent now, the mixing with other cultures is more so.
