Your Scientology contact will very likely be without an answer to this question. If pressed, he or she will probably say that there is nothing they don't like. Does this sound reasonable? Is there any institution, church, charity, school, fraternity, job, group of friends or social club that you have heard, from any of your friends or family that has absolutely no aspects that were a less wonderful than the whole? Even among the most positive groups, there must be something negative, some unpleasantness, some part that needs improvement.
Do you think it is more likely that your contact likes all aspects of Scientology equally, or is it more likely that he or she is not allowed to say anything negative about Scientology?
