I'm reasonably sure bird flu exists but the bird flu "pandemics" sure seem like a fraud based on three lies:

1. That bird flu will spread like wildfire throughout wild and captive bird populations and most catch it and die. (Films and TV really help to sell this idea.) Unless they're claiming there's a new genetically engineered version (they're not), this isn't how viruses spread in the real world. Bird flu is nothing new.
2. That there is a bird flu "pandemic threat". Look at the "case" numbers. Very low. The only actual threat is government overreach: ordering people to kill their birds.
3. That the best way to save birds from bird flu is by killing them. Millions of them. I don't know if they even bothered to try to make that one make sense.
