Where is the line between fetish and mental illness??? Why is it that if someone wants to cut off their own healthy limbs, we are calling this a fetish rather than saying what it is, a mental illness. No rationale human being would want this done. And before people state that there are many fetishes and that people have the right to have them, if any of you had a friend that wanted this done, you would take them to a professional to get them help, you wouldn't be encouraging them to cut off their legs.
