Madison Hippies Accuse Me Of Being A Sex Offender

The subject basically says it all. Two hippies just showed up at my door and asked me if I am or if I live with a sex offender who was previously listed at this address. They are prowling the streets with a list of sex offenders in the area. I don't know what they would have done if I was the guy they were looking for. Are they just trying to intimidate these guys into leaving their neighborhood? It's not like I'm going off in support of sex offenders, but come on ladies, let's tone down the crazy a little bit.
