No Little Hawk, one does not need ALL the known relevant facts to have a valid position. One might reevaluate when new facts come to ones attention. But only a fool would treat arguments from vested interests as facts.

If your Dachshund picks the meat out of the kibble given him by the nasty neighbor next door, the one who complains about dog poo in his rose bushes, without first sniffing it very very carefully, then poochie might end up puking on your carpet on his way to the vet.
