If you think the dairy industry isn't harmful, you need to open your eyes and do some research. Cows only lactate when they give birth, therefore they are artificially inseminated over and over again with what is commonly referred to as a "rape rack". When the calves are born, they are ripped away from their mothers within 48 hours. The mothers will cry out for their babies until their voices give out.
The females are condemned to a life of misery as dairy cows and the males are chained up in tiny pens for weeks. They are not given any space to move and their necks are chained to keep them from licking anything. They are fed a very poor diet and deprived of iron which causes anemia. You know why? Because people like that "tender, white flesh" which only happens when the cows aren't allowed to move or consume iron.
The cows are "milked" by machines which overtime cause their udders to sag and pick up infections. Their udders release puss when milked (which goes into the dairy you consume). So not only are you condemning animals to horrible lives, you are also supporting the meat industry.
Also, milk is completely unnatural. Humans are the only species to consume milk after infancy and to consume milk from another species. The calcium in dairy cannot be properly absorbed by our bodies. Dairy actually leeches calcium from our bones, raising the risk of osteoporosis (the bone disease which causes bone fracture). The countries with the highest amount of dairy consumption have the highest osteoporosis rates - the United States is in the top three. Dairy is also a leading cause of many other health problems, including diabetes, asthma, obesity, heart disease, the list goes on.
Organic only means the cows aren't pumped full of hormones. So when the cows are being mutilated or are sick, they don't get any painkillers or antibiotics. I don't know about you, but that doesn't sound like they're treated well to me.
Sure you can go and search for a small farm that treats their cows well, but you'll still be stealing milk from the calves - the ones that the milk is meant for. And at the end, all those cows end up in the same horrible slaughterhouses.
Honestly it is your choice whether you wish to continue consuming dairy or not. Its a personal and ethical decision that only you can make for yourself.
Even if you want to continue consuming dairy, you should consider the fact that your bones are so weak, most likely because of your dairy consumption.
