I don't think you have to worry about people here being less intelligent than you, they are quite capable of making up their own minds on what information they find credible and what they don't find credible.
The cherry picking of medical studies most often applies to industry funded research, where an industry like meat, dairy, eggs, funds their research only providing their results that they wish to be seen. As you probably know, there is no 'big broccoli' industry, or 'big cauliflower' industry funding research, so studies involving just plants aren't skewed like the meat, dairy, and egg industry studies. There's money to be made by the meat, dairy, and egg industries, follow the money.
Dr Greger isn't the only doctor that is aware that:
The World Health Organization classifies processed meat as a Group 1 carcinogen, which means that there's convincing evidence that it causes bowel cancer. Red meat is classified as a Group 2A carcinogen, which means it probably causes bowel cancer.
Eat it if you want, no one is stopping you. Or eat more healthy food, or eat less meat, do what you want. But don't lie to people and say meat is really healthy.
Your right about one thing, diet isn't the only reason for illness. But chronic conditions like heart disease, stroke, diabetes, those are the leading killers for the US, can all be made much better with a better diet.
