I’m wanting to know if there exists a word to describe the following situation. Someone who finds a silver lining in something is generally considered a good thing. However, I am looking for a term or word to describe that same thing except in a negative way. Someone who finds the positive in something that then undermines the negative in the first place.
An example I could use would be if someone were to say “amputees have better problem solving skills due to their ability to operate normally with missing appendages.” Now, if someone were to do this that would generally be consider not very good and undermine the struggles of being an amputee in the first place. That is what I am looking to describe. Is there a word or phrase to describe the person who is undermining the amputee?
