The use of tolerance comes with varying degrees of indifference to something, with often unstated or deliberately understated degrees of disapproval for that thing. For example, "While I'm tolerant of those that eat meat, I don't personally do it."
Enthusiasm, on the other hand, conveys endorsement. "I'm excited that people are eating meat, though I don't personally don't do it."
Ambivalence immediately comes to mind, but that negates any inclination toward the subject, be it positive or negative.
What word indicates "I think that's fine, but it isn't for me", without the sort of negative connotation that tolerance lends, yet lacks implied or enthusiastic endorsement? What word exists between tolerance and enthusiasm for something?
