I’m not trying to “own” you, don’t be childish. My whole point is: people find things disgusting even if they don’t leave a permanent mark. For you, the threshold is somewhere between brackish dish water and a filled toilet bowl. For other people it’s below brackish dish water. Just accept that other people find things disgusting that you don’t find disgusting, don’t try to tell them “but it doesn’t leave a permanent mark, what’s the issue”.
