They do not reply. There is a person who has a survival products business, just south of Olympia WA, that bears the name of Ancle, who may or may not be associated with these bot-generated "Tokyo Rose" type of spamish comments. That is all I have been able to figure out. Best, I think, to just flag and move on without bothering to read the propaganda. If they are really leftists, trying to waste your time (a legitimate political combat tactic), then you are foolish to reply. If they are simply devious marketers for survival products, then they will probably suck in a modicum of shallow thinkers. Caveat emptor.
