I'm not so worried about dividing humans and LLMs as dividing humans from each other. Sure, LLMs are not humans, and that's a valid distinction, but the word "clanker" is used by humans, and there's already a divide between humans who think it's OK to use a slur if it's directed towards a group they don't like (I don't mean you here) and people who don't.

I'd think less of someone who was gratuitously swearing at a dog not because they hurt the dog's feelings, but because they were being gratuitously negative.

It does, and the use of "clanker" I've seen was generally meant as a slur. It's not a neutral word in any context I've seen it in.

True, but I also think that "clanker" is fairly far towards one end of the spectrum, not really near the middle.
