Thats why I watch almost exclusively British mystery shows now. They are far less PC than American shows. In the US if you have a gay character or suspect of color, that will not be the murderer! In the UK the person just may be the murderer and is not held up as a perfect person.
The big exception to political correctness in the UK is Doctor Who, and not coincidentally the producers since the 1980s have all been gay. It is so politically correct these days, not just casting a female doctor, that I gave up after 40 years.
