Are you suggesting that one simply advertise the existence of good vegetarian recipes without mentioning surrounding reasons for reducing meat?

I agree with Viliam_Bur that this may be effective, and here's why.

I bake as a hobby (desserts — cakes, pies, etc.). I am not a vegetarian; I find moral arguments for vegetarianism utterly unconvincing and am not interesting in reducing the suffering of animals and so forth.

However, I often like to try new recipes, to expand my repertoire, hone my baking skills, try new things, etc. Sometimes I try out vegan dessert recipes, for the novelty and the challenge of making something that is delicious without containing eggs or dairy or white sugar or any of the usual things that go into making desserts taste good.[1]

More, and more readily available, high-quality vegan dessert recipes would mean that I substitute more vegan dessert dishes for non-vegan ones. This effect would be quite negated if the recipes came bundled with admonitions to become vegan, pro-vegan propaganda, comments about how many animals this recipe saves, etc.; I don't want to be preached to, which I think is a common attitude.

[1] My other (less salient) motivation for learning to make vegan baked goods is to be prepared if I ever have vegan/vegetarian friends who can't eat my usual stuff (hasn't ever been the case so far, but it could happen).
