To paraphrase Max Planck:
Veganism will not triumph by convincing the few flesh-eaters about the moral imperative to leaving off eating and enslaving our fellow earthlings. But rather because its opponents will die, replaced by freedom-oriented generations to come.
We contemporary vegans will die too, of course. Die the precursors, the vanguards to a new era of enlightened liberty.
“A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.” ~Max Planck
