Sentimental Vegetarianism (page 160)

The Sentimental Vegetarians are the most numerous and illogical of the
different sects of dietetic vegetarians, quasi-vegetarians,
frutarians, nutarians and the raw vegetable nourishment stalwarts. If
the pretensions of the sentimental vegetarians are to be taken seriously,
not only must humanity forgo all animal foods, including milk and
eggs, from ethical motives, but true to the essentially democratic principal
of "sois mon frere, ou je te tu," every single race of mankind should be
constrained -- by force of arms failing peaceful persuasion, since the
offence is greater in the eating than in the killing -- to abstain
from meat nourishment for all eternity.

After making the world safe for vegetarianism, the next step would be
the organization of armed, vegetarianized, humanity (or vegetarianized
armed humanity - it does not matter which, but propagandists would
declare there was a world of difference) to prevent non-carnivorous animals
being devoured by carnivorous, and to put a stop to the outrage of
carnivorous animals preying on each other.
