But I can't find the actual incident, only mentions of what happened.
I discovered there's a wiki keeping tabs on Social Justice Warriors and Kendall has her own entry, which discusses the funeral home incident:
Karnythia is especially notorious for checking up on a woman who claimed on LJ that her baby had died, going so far as to call up the funeral home to validate the story. There are Gentlefailer discussions about that here, here, and here.
Does anybody out there have any screen caps or other direct evidence of what happened, as well as the name of the woman whose baby died? And the name of the funeral home?
