Subtly anti-ag: one-sided articles in liberal news outlets about the dangers and social injustices associated with ag tech like GMOs, and books like The Omnivore's Dilemma. Purporting to be unbiased but might not be.
Blatantly pro-ag: research funded by agribusiness or the USDA. Clearly intended to benefit the industry.

But I wonder what is "subtle anti-ag" or "blatantly pro-ag" means in this context. Can you give some examples?
