I think I'm interested in words that completely avoid even what you've called mostly only etymologically problematic words for two reasons.

1 - different places use different words differently and so while it may only be obscurely problematic in one place, it may not be in another. For example, where I'm from, 'lame' does get used in the older ways.

2 - I think it's interesting for its own sake to see the huge range of words available that aren't bound up in shitty histories. And then also to ask what the point of using words with bad histories when we have so many that don't.
