Imagine thinking that telling people on the internet to not have kids is an effective strategy against climate change, while downplaying the importance of going vegan. Continuing to be an animal abuser is also more than a kick in the gut to all the animals who are born in extreme captivity, live a life of constant torture and rape, only to be slaughtered (usually in childhood) just so people can satiate their gluttony for a little sensory pleasure and delude themselves into thinking they need to do that because they've been trained by unscientific marketing teams into thinking it's the only way they can get protein.

On the other hand there are a lot of antinatalists in the vegan communities. So if you went vegan, you'd be in good company.
