There was a white teacher at my school who was the head of the diversity department. She constantly went on about how she's married to a black man. When she had a baby, she brought her baby in and went on and on about how he was biracial.
Would this be considered racist?
As for the mentioning killers' religions and so on, newspapers tend to use minorities as identifiers. For example "Lesbian Gets Caught in Sex Scandal" or "Deaf Man First Man On Mars" or what have you (just making up the titles).
And some minorities take precedence over others. For example, to vaguely bring the thread back on topic, from the conversations I've had and newspaper articles I've read, there is a lot of talk about how David Paterson is blind, but there is very little talk about how he's black. So in a way blindness takes precedence over blackness when using a minority identifier.
