The point of the video is that dairy farms generate surplus male calves, which have to be disposed of somehow. The male calves may be treated well when they're being raised but it's those very same male calves that are often shipped abroad from countries like Germany to meet the fate you see there. This is an intrinsic part of the dairy business because cows must be kept pregnant to produce milk. I think you should watch the whole thing because you missed the point.
At least in the US, 80% of the milk sold is from factory farms, where cows are certainly not treated well.

2) I speed watch through a good part of the documentary. 100% there is some horrifyingly bad footage there. I feel its fair to note what I saw in Germany / France the animals are treated well. The horrifying footage was largely shot in developing countries in the middle east. This supports what my original comment was about, the information being provided shows a skewed view. And I haven't seen anything to change my mind that in some regions animals are treated well and looked after. And in others, they are not.
