I understand that "visceral" with respect to a reaction or feeling is a very intense one. But I haven't found an authoritative source that describes a visceral reaction as being an exclusively bad one. Examples:
Visceral = bad?
- Seeing an intruder in your home.
- Be suddenly and intensely repulsed by someone's comment.
Visceral = good?
- Being moved to tears after an unexpected photo of something good.
- Figuratively having your wind knocked out in a "love at first sight" situation.
Sorry my examples may not be as good as they could be. Does visceral mean just a bad feeling or can it mean a good feeling in your gut too?
