It is true that dairy cows have their calves taken away; so do dairy goats. I maintained my own herd of goats from when I was age 11 on, so I've taken lots and lots of babies away. It was absolutely essential for disease prevention and to feed the babies correctly.
In most dairys what happens to the bull calves?
The dairys that I have been to are in New Mexico. Here's a picture of a typical scene at one from an unbiased source http://spectre.nmsu.edu/media/photos2.lasso?i=267
Most of the dairys are large (1500+ cows). The dairys are mostly located in the south-eastern part of the state. It's an arid, dry climate, and none of the cows are kept on pasture. Yet, it is one of the nations centers for factory dairy farms. There is a mozzarella cheese plant there, where a lot of the milk collected goes. This plant supplies a large portion of the world's mozzarella cheese, and sells to major pizza chains.
As far as fur goes, even if you are raising the animals humanely and killing them painlessly by gassing, do you think it is better to do that then just leave them alone in nature? Do you think that the fur industry is so essential to the wellbeing of people in the world that there would be much human suffering if we no longer used fur? There are some reasonable arguments out there for eating some meat (although it's not my view) in your diet, but where is the need for fur?
Here are a few more extreme quotes
"`Why have any men at all?' wrote Sally Miller Gearhart in a 1982 manifesto titled `The Future–If There Is One–Is Female.' Gearhart is an advocate of ovular merging, a process that involves the mating of two eggs, which has been successfully accomplished with mice. Only female offspring are produced. (from the Men's Rights agency, warning of the dangers of feminism, or at least extreme feminism).
Civil rights laws were not passed to protect the rights of white men and do not apply to them -- Mary Frances Berry, Chairman, US Commission on Civil Rights
These quotes are thrown around to support the notion that we do not need a women's rights movement or a civil rights movement, by groups that are opposed to any movement in that direction. So, because there are extreme views within the movement, do we ditch the movement entirely?
Yes, posting animal cruelty videos causes a strong reaction, and the people who put them up there are hoping that that reaction causes people to act. How they act may vary from treating their dog or cat better, caring for other dogs or cats in their area, pushing for legislation to protect pets in their area, rethinking their entire relationship with animals, giving up meat, going vegan, or even joining with an animal rights group.
Just because you might not support all the goals of an animal rights group, is the only response to support the status quo? Can you be part of the animal rights movement without supporting everything that everyone in the movement says?
