Younger people tend to be more progressive, but it's not because they get more conservative as they age. It's because the general viewpoint on certain issues becomes more progressive all the time. Things considered progressive 30 years ago, such as gay rights, are considered normal now. Things that are progressive now will most likely be considered normal in the future.
