interesting.
Sounds a lot like ethical vegans to me.
If you can't understand that distinction...
If you want to make the case that your daughter is a really nice proselytizer for healthy eating, and that vegetarians are really awful, we can just compare anecdata.
You went out of your way to quote second-hand sources for "filthy murderer" vegans, suggesting it hasn't been your experience. How many people who've called vegetarians pansies do you personally know?
As for "proselytizing"... rather than bickering over the word, bicker the intent. Do you think it's a bad thing for a non-vegan to cook vegan food for a vegan? To teach them about cooking and nutrition? To encourage them to make their own food rather than eating something put in a bag in a factory?
I don't see how what she's doing can be reasonably considered negative. So if it's proselytizing, then proselytizing is itself not a negative. If you think it's negative, I'd love to understand why.
I don't see how that can be considered negative either. Can you?
If my daughter was just getting on the vegans she knows for eating junk food, not good food like she does, it would be one thing. Instead, she leads by example, teaching them to be better and healthier vegans.
Something analogous would be a vegan making a beautiful, delicious vegan meal for a meat eater who thinks a vegetarian diet is dull and poor in nutrition. That's not proselytizing, imho.
And at the very end you're trying to go back on admitting your daughter is proselytizing, by complimenting her cooking skills. I think you're quite confused about your principles.
My daughter, a budding chef and foodie with many vegan friends, gets a lot of grief over it too. For her part, she's trying to get the vegans to eat decent food, as most of the ones she knows eat what she calls "vegan junk food" - factory products rather than actual cooking of fresh ingredients.
