It’s not as clear cut as this, a lot of the studies that suggest this don’t stand up to scrutiny, with for example some having numbers of estimated birds killed by cats over the total estimated bird population. Also the fact that the majority of kills by cats are already weak or sick animals, animals that would die soon either way, and not really affect the total population. The only ones that seem legit and suggest an effect on the population are from small islands.

Are you telling me that I should have diluted some bullet material, instead of trying to start by shooting myself with a small caliber and work up my immunity from that? All this work, wasted!

To add to your point, it used to be that the village idiot was just that, known for it, and shamed or shunned. Now that they can connect to other village idiots, they can find a community of like minded idiots that reinforces their beliefs.
