Edit: Surprised at all the vegans in this thread. I didn't think there were so many of you. I'm glad you care so much about animal rights, that you're willing to forego eating them and using products made from them.
If you're not vegan and have moral objections for this, maybe you should look at yourself first and all the animal abuse you sanction by eating animals and using animal products.
Did you know dairy cows have to be pregnant to produce milk? They're artificially inseminated throughout most of their lives. I hope everyone complaining about this also complains about ice cream and cheese. Or else they would be hypocrites who just want to blame others but never look at themselves.
It's not controversial, most people think it's stupid. Controversial would be if so many people agreed with you that it would polarize the society. Which you might think is what happens, but it's really not.
Most people know that a human's life is more valuable than an animal's and think you guys are a little crazy. Treating them with dignity is fine by me, but pretending they're on the same level as us is not.
