My understanding is that people object to this as it is a means of defining them rather than describing them. In fact, I know people who would be insulted with the use of "autistic people" as opposed to "people with autism"

One term encourages the idea that they're people first-and-foremost, with the adjective used to describe a particular subset of people.

The other removes the emphasis on them being people and is pretty depersonalizing.

As you can imagine, it's much worse when it's a historically marginalized group--as an example, fewer people will care if you say "blondes" vs. "blonde-haired people".

I don’t deliberately go out my way to offend anyone but nor can I be responsible for offending someone looking to be offended, it’s a fine line.

Though this thread has been fascinating.

Yeah, but it's also perfectly fine to use it. Jews use it, Wikipedia uses it. The commenter also said "the Palestinians" in the very same comment in which they said "the Jews", making this whole subthread slightly silly. Not that dragging conversation into accusing others of "sentiments" they cannot disprove and one cannot prove them to have, before or even instead of dealing with the factual stuff that all parties can examine and elobarate on, is ever not silly.
