The analogy I like to use in debate is housekeeper. Some housekeepers do it to pay the bills and support their family, some actually enjoy the act (believe it or not), and some are brought into the country illegally and forced into indentured service and even abused (while someone else keeps their passport). We need to stop people being trapped into it obviously, but are you going to outlaw housekeeping to do it? Even if you would never "stoop" to being a housekeeper yourself and couldn't understand someone wanting to do it for a living, is that reason to take it away from those who think differently than you and choose it?
