My grandparents owned a farm and my dad was raised on one. I don't think everyone treats them the same. There were no bellowing or crying cows at all. They did both dairy and beef depending on when. More beef just before they rented out and eventually sold after my grandfather died. I also lived on a farm in Germany in the summer for dairy cattle. Saw quite a few calves. Again though no bellowing or crying.
I'm definitely not saying you have to change your ways, but sometimes what people say about farming bugs me because while my family is a bunch of racist jerks, that is how many still make their living and how my disabled aunt was able to have a nice life and live comfortably on the sale of things after the death of her mom and dad. It was my life and I don't have any ill feelings towards farmers. In fact I spent a lot of time petting cows and just watching them grow and such both at my family's farm and in Germany. Not to mention pigs, sheep, and chickens. Okay I hate chickens. I have zero guilt about eating chickens after growing up around them. God they're stupid animals. But cows? They are sweet animals that deserve to be treated right during their lifetime.
Eat how you want to eat is my thought - don't guilt people into doing what you think is best. (that's directed at everyone here - including those poking fun at vegetarians)
Ours was beef cattle and hogs before the dairy operation. I know some of the stuff she talks about does happen at huge commercial operations but its not like every farmer or rancher is like that...at all.
