Any moral superiority vegans may or may not have claim to is lost in the cancer they expose us to during debates...

On a purely ethical level, people debating in favor of veganism with these stupid dialogue trees have caused more harm in the world than had they participated in factory ranching / meat consumption. They have permanently undermined their cause, preventing people adopting veganism, causing people to intentionally consume more meat to spite them. I grilled up some pork belly out of spite. Bystanders to this debate have decided to harm themselves due to the pro-vegan.
