I think the reason the stigma exists is because anyone (and unfortunately it does happen quite often) can claim to be psychic, and be able to see, hear, or communicate with spirits. And I think the popular belief is that if someone has made it to a level of being a public medium, they must have proven themselves at some point.
The truth is, there are probably more public and "for hire" psychics and mediums which are not what they say, than there are non-public ones. In the short time that I've run this site, I've had the pleasure of talking to many individuals who have been blessed with gifts. Some are public, but most are never heard of or from.
