Given the post dates on Edward's FB page, Waffle House may have lost a cook. His most recent post was June 8th.
Optometrist brother Thomas, the relevant DU-member, most recently posted in mid July, but nothing about his brother being sick.
If Edward did indeed die, he and his brother may have estranged, hence the lack of mention noted above. If Edward did die, his family has my sympathies.
As for DU-member Thomas ... since starting to post on news politics discussion sites I lost my father, my MIL, and a cousin with whom I had been somewhat close. If I mentioned any of their deaths, their politics weren't, nor was I asked. IMO, it evidences the ugliness of DU-member Thomas' character that his first impulse was to politicize his brother's death.
