>I suggest not waste your time on it.

I don't understand this. Why not?

You recommend a documentary with opposing views instead; should we only read and watch things that we agree with?

>Whoever lives in a cosmopolitan city knows this is not true, or not anymore.

Vegetarians compose about 3% of the population. I'd say that's a "margin group". If you live in a coastal city in the US, vegetarians may be over-represented.

>It is that supermarkets choose to put the "high price" on produce all year long, except for a discount crop maybe. This is because produce does not pull customers.

Blatantly false where I live. Produce is substantially cheaper all summer and into the fall than it is in the winter when we have to import vegetables from around the world.
