Ultimately, he argues, every sentient being wishes to avoid suffering and death. And even if it were possible to treat all food animals as cherished pets, raised and slaughtered under the gentlest possible conditions, in the end they are still killed for the purpose of fulfilling human pleasure or convenience. (The killing also applies to dairy cows and egg-laying chickens, who don't simply live out their lives to die peacefully of old age even on the smallest family farms.)
I just finished reading Gary's latest book - co-written with Anna Charlton - Eat Like You Care, which explains the above and addresses a great many frequently-asked questions about nutrition, ethics, and other situations where many believe eating animal products would be justified. Little of the information was new to me, and I didn't agree with everything the authors wrote or how they phrased their arguments (the repeated references and comparisons to Michael Vick's dog fighting I thought were excessive and somewhat counterproductive). But it did make me think about how I've been addressing veganism, and how much I've been burying a topic that is of great importance to me out of fear of causing offense or being socially isolated even further than I am now.
I've never considered myself to be an animal rights activist, because I associated these people largely with fanatics who consider animals to be morally equivalent to humans, and do things like throw paint on fur coats or break animals out of laboratories. Gary does not think this way nor advocate these activities. He acknowledges that in the choice between saving the life of a human or an animal, the human always wins. But he also notes that unless you're stranded on a desert island, in a lifeboat, or in some remote desert or arctic area without access to plants, this does not excuse eating animal products. He does not advocate giving animals legal personhood or changing the laws to prevent their consumption, either. He simply asks that if people agree that eating animal products causes unnecessary suffering and death, that they voluntarily stop eating all such products. No additional activism necessary.
I'm sure many would be turned off by Gary's arguments, finding them preachy. I've always been averse to proselytizing myself. But then I think of Penn Jilette, who is no vegan (quite the opposite) but an atheist and quite engaging author and personality. In his book God, No!, amongst other places, he has stated that proselytizing doesn't bother him at all; in fact, he welcomes it. He believes people should speak up strongly for what they believe in. He's fine with Christians praying over him, arguing with him, trying to convert him from his sinful ways. (He also frequently reads the Bible so that he can counter Biblical arguments quite effectively.)
As I've read and heard from other sources, for some Christians, they consider it obligatory to try to get people to come to Jesus in the same way that they would consider it obligatory to try to save someone from drowning. They literally believe the person's eternal soul is in danger and they need to get them to believe in Jesus in order to save them from hell. They sincerely think they're doing a selfless, compassionate act, even if to most of us they seem like annoying fundamentalist nutjobs, or worse.
I don't want to be seen as a fundamentalist nutjob. Or an asshole. (Penn Jilette, in contrast, would be fine with this, admitting in the first chapter of his book that he is an asshole.) But at the same time, I believe our animal-based agriculture is literally killing us - humans, animals, and entire ecosystems - and that it's urgent that we reverse this trend. Gary's writings have convinced me that halfway measures and welfarist approaches (which even organizations like PETA are now advocating) simply aren't going to make any real difference.
But how to approach this subject without turning people off? No doubt I already have. But I no longer feel comfortable watering down my views on this issue to make them more palatable. The only question is how to advocate in an effective way.
