Many people will also not reduce food waste, for exactly same reasons you won't stop eating meat. Convenience, habit, cost, time investment.

Both are true: reducing waste and adopting a plant based diet are great ways of reducing your footprint.

The number of vegetarians/vegans is growing quickly. I'm not convincing you of going vegan. You are convincing yourself to keep on eating meat despite the scientific facts and moral consequences.

implicitly comparing Jews to cattle

Yes, it's a tasteless comparison. I'm a German. Hello neighbor, nice to live in peace.

The comparison also falls flat because while the Holocaust was a genocide, meant to eradicate, factory farming is the polar opposite.

The population size of factory farmed animals is usually way above natural levels, because we farm them. A philosopher even called it an evolutionary win for the farmed species (which does not justify any harm done to individuals).

There are more ways to express 'very bad' than comparing to the Holocaust, and many reasons not to, if you understand it.

*implicitly comparing the treatment of Jews during the holocaust to the treatment of cattle today

also, you can compare two things without equating them

I think if you actually cared about the words you wrote, you wouldn't have used them as the basis of a lazy strawman to win an argument on the internet against veganism

Here are some quotes for you. From holocaust survivors and their relatives.

“I totally embrace the comparison to the Holocaust. I feel that violence and suffering of innocents are unjust. I believe that the abuse of humans and animals and the earth come from the same need to dominate others. I feel that I could not save my family, my people, but each time I talk about cruelty to animals and being vegetarian I might be saving another life. After knowing what I know about the Holocaust and about animal exploitation I cannot be anything else but an animal rights advocate.

-Susan Kalev, who lost her father and her sister in the Holocaust

“I believe in what Isaac Bashevis Singer wrote, ‘In their behavior towards creatures, all men are Nazis.’ Human beings see their own oppression vividly when they are the victims. Otherwise they victimize blindly and without a thought.” [tweet this]

-“Hacker,” Animal Liberation Front member & Holocaust survivor

“What do they know—all these scholars, all these philosophers, all the leaders of the world? They have convinced themselves that man, the worst transgressor of all the species, is the crown of creation. All other creatures were created merely to provide him with food, pelts, to be tormented, exterminated. In relation to them [the animals], all people are Nazis; for the animals, it is an eternal Treblinka.” [tweet this]

-Isaac Bashevis Singer, Yiddish author, Nobel Laureate, & Holocaust survivor

“I spent my childhood years in the Warsaw Ghetto where almost my entire family was murdered along with about 350,000 other Polish Jews. People sometimes will ask me whether that experience had anything to do with my work for animals. It didn’t have a little to do with my work for animals, it had everything to do with my work for animals.”

-Alex Hershaft, Farm Animal Rights Movement founder & Holocaust Survivor

“When I see cages crammed with chickens from battery farms thrown on trucks like bundles of trash, I see, with the eyes of my soul, the Umschlagplatz (where Jews were forced onto trains leaving for the death camps). When I go to a restaurant and see people devouring meat, I feel sick. I see a holocaust on their plates.” [tweet this]

-Georges Metanomski, a Holocaust survivor who fought in the Warsaw Ghetto Uprising

“I dedicate my mother’s grave to geese. My mother doesn’t have a grave, but if she did I would dedicate it to the geese. I was a goose too.”

-Marc Berkowitz, Animal activist & survivor of Josef Mengele’s “twin experiments”

“In 1975, after I immigrated to the United States, I happened to visit a slaughterhouse, where I saw terrified animals subjected to horrendous crowding conditions while awaiting their deaths. Just as my family members were in the notorious Treblinka death camp. I saw the same efficient and emotionless killing routine as in Treblinka, I saw the neat piles of hearts, hooves, and other body parts. So reminiscent of the piles of Jewish hair, glasses and shoes in Treblinka.”

-Alex Hershaft, Farm Animal Rights Movement founder & Holocaust Survivor

"Jews have been, while animals still are, treated like nothing, as if their lives don’t matter. You can also compare the two holocausts this way. [...] Go to the nearest cow or pig slaughterhouse and remove the animals and replace them with humans. You have now re-created Birkenau."

-Gary Yourosky

Those 100 corporations make materials that everyone else uses (mostly O&G) and the consumption and use of those materials (by we the consumers) is responsible for 71% of GHG emissions.It's not just 100 companies burning coal for funsies

The point is that even without that reason you wouldn't have any kids. It's not the cornerstone of your childfree-ness. Neither is it for me, which is why I recognize that it's morally lazy to rest on the imaginary laurels of not birthing children.

By that logic, every parent could ALSO claim they are doing their part for the earth. Simply by not having EVEN MORE children. Hell, maybe they are better than you because you only didn't have 2 kids, but they didn't have 4 additional kids. Thats twice the savings, twice the reason to not make the world a better place and blame everyone else!
