I didn't really read all of it, just quickly skimmed over it. That was only one of the websites I saw that mentioned how unhealthy milk was, however. There are many other websites that say milk comes with a lot of bad side effects. I don't know if it's true and I never noticed any of the downsides myself.

There's even this: http://www.notmilk.com/
Obviously you shouldn't just believe anything you read on the Internet, but I do think some of the mentioned things on all those sites make sense. I'm sure milk comes with its own pros and cons and that PETA and some others are making it sound worse than it is.
