It's an oof because it shows, yes, we could live happily coexisting with animals without unnecessarily exploiting, enslaving, abusing and killing them for commodities and entertainment, which we have alternatives for. The future is vegan/plant-based and animal rights are respected in a progressive world.

Hence why veganism is a moral obligation to animals. It's indefensible to kill or exploit/harm an animal without their consent (which they can't give), and which clearly isn't in their best interests

Unnecessarily killing or harming a sentient individual is wrong, full stop

It's "at a loss for words", not "at a lost of words".

CNN’s Wolf Blitzer seemed at a loss for words at the justification being used to bomb a refugee camp in Gaza.
