2. Going back to my example, the whole "if we let them do X, where does it stop?" was a big part of 90s discourse regarding LGB rights. So far, the slope hasn't slipped into any of the scenarios people brought up. Language changed a bit. Some people felt more included by society. I suffered no injury beyond letting go of the notion I was entitled to use certain words to mean certain things.
I found other ways to convey those things. It turned out fine.
I apologise if my analogy made you feel uncomfortable, and I'd be happy to learn a different analogy which expresses the same idea just as clearly. If there isn't an effective alternative analogy, though, then it might appear as if you are using claims of discomfort to limit legitimate criticism of your ideas, which I trust isn't the intention.
I appreciate you responding to my criticism despite my analogy, but I was concerned you might try to discourage or prevent people using such an analogy in future, without offering an alternative (and despite me having no ill intent behind it).
As for why I used an analogy, I don't know what reason will satisfy you. People use analogies to help other people get an intuitive sense of an idea which might otherwise be hard to explain. If you understood my point without needing the analogy then that's great, but I don't want to assume that analogies are never helpful.
1. I'm not comfortable with the analogy.
