Perceived threats to our kids can really turn us into different people...willing to take all sorts of measures that we otherwise wouldn't give merit to.
Agreed. Ask me offline / in-person about the convicted, on-parole, child molester who moved in 5 houses away from me (50' over the limit for a child-ped domicile from a school) and proceeded to buy a little fluffy dog that he took for walks and stopped to talk to the little girls in the neighborhood. Things didn't end well for chester-molester though that's a story that some of our more live-and-let-live minded members get pretty worked up about.
This time though? Purely from his narrative? "Confronting" an older handicapped dude after knocking his drink off the table when NHV continually failed to keep his kid out of their drink cup? That behavior is over the line to me.
