I would say, this guy letting someone else's dog out of its kennel and playing with it, without the family's permission, is a huge red flag and the fact that he is on some sex offender registry makes it all the more creepy.
I also question Nuclear Dem's recidivism rate theory for pedophiles but it would have to be something I need to research more. My understanding is pedos can't be cured, or normally aren't cured.
But yeah, other than making fun of the OP for belonging to a site that condones pedophilia while expressing fears for someone who definitely doesn't mind violating other people's borders, I would tend to the side of concern.
But, I wouldn't ask for help from the DUmp.
