A pervert at heart is a pervert at heart ... and no doubt the potential opportunist.
This is an important point. Since every sexually aware human being on Earth has the potential for "perverted" behavior and the idea that someone who has feelings you may find abhorrant is somehow different from you is just a denial coping mechnism to shield oneself from the admission of ones own particular abhorrant feelings. I think all should realize how dangrous the above additude is.
