Dev, if you look back, she's definitely been veering towards preaching rather than having her say.
That said, 80 years ago, my dad's family (not badly off as his dad was a bank manager) would perhaps have had one joint of meat a week, which would have been made to last for several days, with fish on Friday, perhaps sausages on Saturday and a bacon for a fry-up on Sunday. Westerners do eat far more meat now than even a few generations ago. The planet's resources can't sustain this exponential growth in livestock rearing and its effects vis-a-vis deforestation, especially with the rapid growth of meat-eating in the far east. But calling people immoral because they do something our species evolved to do is just plain silly.
