Determining what exactly is profane, obscene or non-family friendly is something the Supreme Court has wrestled with in vain for years. Free speech seems to have won out over decency. In evitably, you will have one racial group or another complain they are being singled out for enforcement of the guidelines more strictly than other racial or ethnic groups. But there is a solution.
However, if the dress and grooming standards were clearly posted in the parking areas and at the entrances to the Parks many individuals would voluntarily comply. There are a number of shops in Down Town Disney where appropriate clothing can be aquired.
The process of enforcement could begin by sending the annual passholders a mailer listing the new dress and grooming guidelines. Then the signs could go up sometime later in the parking lots and at Park entrances. These guidelines should be strictly enforced and photos taken of each offender and filed away for possible future legal defense in the event an individual wishes to sue the Disney Corporation.
Obviously some people will just refuse to comply. The want to be as vulgar and disrespectful as possible, or maybe they might have issues with authority. Whatever. They won't be returning to Disneyland and that helps the overcrowding. Those undesirables who won't be coming back are probably the same individuals responsible for most of the vandalism and damage to the Park anyway. As a result there are big savings in Park repairs. Another bonus!
I would allow beards and moustaches though. (Since my heart attack on Main Street, I have a machine that helps me breath at night. The facial hair provides and nice buffer between my skin and the mask so I don't get blisters on my face.)
What should be done about piercings? Remove them or cover them with tape or band aids?
