I think part of the problem isn't just the people putting out these lies, but the people towards whom it is directed. Too many of the population can't even find their city, or in some cases the state in which they live, on a map. They do not hunt, or even know about hunting.
The media is biased as to what they put out, and is usually against RESPECTABLE hunters. The only time you hear about hunters is when they do something stupid.
I view most of the animal rights groups like I do Jesse Jackson or (Rev?) Al Sharpton. They make a lot of noise without knowing/caring about the facts, but do very little otherwise to remedy the problem.
Most people don't realize that hunting/conservation groups like Ducks Unlimited do more for animal conservation, population contol, environmental preservation etc than ALL other "animal rights groups" combined.
