The scenario presented was:

   Let's say you have kids, and another parent tells you "hey, that guy asked my kid to get in a car with him, you should be careful"

and this and close variations of this have actually happened to me and to others I know over the course of the past 30 years, including straight up accusations of "that guy's a known pedo with a record".

My observation over three decades is that not everybody with mud slung at them actually deserve that, sometimes it turns out that the accusers have some other beef and no filter on attempting to make others look bad.

Further, I can cite many examples of upstanding professional folks with zero accusations and solid reputations actually being revealed after many years to be actual child molesters. - Priests, Police, Sporting and Entertainment stars, Child Psychiatrists, etc.

But sure, you can rush to judgement on others as you choose, many do.
