You two are just well after your time, for, it had been written long ago:

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.
