What is your opinion on "person first" language? (See inside for details.)

I am finishing up my endorsement to teach secondary special education and one thing I am finding is that my instructors are sticklers about using “person first” language. In other words instead of saying “my quadriplegic boyfriend” I would say “my boyfriend who is quadriplegic.” What I find interesting is that the able-bodied people I come across in this department are a lot more picky about the use of person first language than the folks I know who are disabled (See what I did there? Instead of disabled folks I wrote folks who are disabled.)

Do you think it is a common courtesy kind of thing or is it political correctness taken just a bit too far?
