Yes, our limitless creativity in inventing and executing moral abominations will go on.
But what has to stop is the needless, heartless hurting and killing of innocent, feeling, suffering victims just to satisfy our tastes in foods, fashions and entertainment that are essential for neither our survival nor our health.
And that is the overwhelming majority of the moral abominations and suffering on the planet today (and perhaps the impetus and inspiration for all the rest):
As to waiting and gradualism. I can wait to stop smoking, because there the only one I am hurting is myself. But if I treat my meat-eating, fur-wearing and bull-fighting habits the same way, it is like leaving my neighbor under whip and chains while I contemplate whether I’m ready to give them up.
