Final answer:
Necrophilia is a paraphilic disorder involving sexual attraction to corpses, not the urge to start fires, which is known as pyromania. Depending on laws, necrophilia can be a dangerous sex offense.
Step-by-step explanation:
The term necrophilia does not refer to the irresistible urge to start fires; rather, it relates to a paraphilic disorder involving a sexual attraction to corpses. The term you might be confusing necrophilia with is pyromania, which is the compulsion to set fires. Necrophilia can be considered a dangerous sex offense depending on jurisdiction laws. The historical account of the brutal lynching of Fred Alexander in Leavenworth, Kansas, a horrific act of community-sanctioned violence and white supremacy, does not specifically relate to necrophilia but showcases the extreme and barbaric nature of punishments for alleged crimes and the deep-rooted racism in the past.
