Honest question, asking for informed responses: How harmful is second-hand vape?

Littered cigarette butts don't biodegrade.

Second-hand smoke causes cancer and the smell lingers on material.

Does other people vaping near you in an enclosed space have a meaningful physiological effect or otherwise? Or is it just association with second-hand smoke that people decry?

Even if it's 100% safe, which it isn't as are every other particulates you inhale, I don't like it, I don't want it. I don't walk around farting in elevators and burping in my fellow train commuters' faces even through it's perfectly safe, it's just basic common sense and politeness.

The vapor droplets contain the nicotine and other dissolved particulates so yes. And there are numerous studies showing heavy metal dissolution into them. I avoid them like the plague.

Anecdotally, it seems to depend on the liquid. Some are very thick and give me an impression like I can’t breathe. Others aren’t so bad, but have an extremely vile smell.

I’d say I’m not particularly prejudiced against vaping in general, I actually do vape from time to time.

Yeah it makes his "blood boil"

Honestly for most people their dislike of people smoking/vaping in shared areas is first about the smell, and only second about the health risk.
