Again, I go back to my example.
Were LGBT activists "forcing me" to change the way I used the word "gay"? Sort of. Did doing so hurt me? No. Did it benefit them? They say it did. Was it for "nothing"? They say it wasn't.
Language changes. I'm not going to waste a lot of energy worrying about it.
At the time, I thought the change was ridiculous. It took me a few years to realize I was just being petulant.
1. I'm not comfortable with the analogy.
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'm not sure why you need an analogy to get your point across.
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.
