There are hundreds of freepers that pretend to know about modern US agriculture. Just start a discussion involving the carbon cycle, GMOs, pesticide use and they come out of the urban woodwork as experts.
Thats a ridiculous bunch. Right up there with those who think welfare subsidised monoculture bank slavery of the last 50 years is modern or those who insult anyone without 1000 acres and 1000 cows as a hobby farmer necause they coulnt figure out how to make more with less.
