Oh why do I open threads like these.....the ignorance makes me want to put my head in my hands and weep....
Firstly, if it is a fact that the dairy industry is very cruel. Just type the words into google and you will come up with page after page of evidence for this. Mother cows are repeatedly impregnated, have their babies taken from them and cry for them for days afterwards, have short, miserable lives until their bodies are completely broken and they're sent to the slaughterhouse to be ground up for pet food. Often they are so spent that they can't even walk to the vans that transport them to the slaughterhouse. It's utterly disgusting.
If you are a reasonable, intelligent adult you might recognise that this is something exploring and might even consider changing your diet accordingly.
If you are an ignorant, self centred twat, you will probably do as many of these thread have done and refuse to educate yourself and instead make utterly pathetic 'jokes' about lovely cheese and milk chocolate.
In that case, I dare you to watch this. Seriously, click the link if you have an ounce of integrity and the slightest desire to know how your eating habits impact on other living beings who believe me, have just as much right to live decent lives as you do.
Thankfully, people who snigger on about cheese and lovely bacon are slowly but surely a dying breed and people are slowly waking up to the fact that we cannot go on like this.
Oh, and animal protein leaches calcium from the bones, so calcium does not protect you against osteoporosis. Again, google it. The dairy industry is massive though and has deep pockets, and a lot of marketing spend goes into persuading us of its benefits.
It is pretty depressing that a thread like this gets the OP ridiculed (and probably me now though I don't intend to come back to view the abuse) but something about a car parking space and what the OP's MIL said to her gets 500 posts.
