Today I also trust a vegan stamp more than a vegetarian one when it comes to food labels. I also learnt that while vegetarian mainly meant strict vegetarian in sweden until the 1990s it wasn't so in the anglosphere. There was some rich biblical folks who wanted in on the word and diluted it to mean lacto-ovo-vegetarian in 1847.
I was not a wee lad in the 1840s that's for sure.

Regarding products from insects I don't really see how them having an exoskeleton makes it more okay.
Regarding lanolin I'd say its the same as with wool. The sheep that was sheared has been or will be slaughtered and buying the byproducts aid that reality.
