A mere coincidence! And anyhow shouldn’t the proper term be “knifepersons”? Shame on them for assuming gender!!! /s;)
Oh no!
It is perfectly proper to use a negative stereo type in reference to men as long as the race of the man is white or unknown.
However should the race of the man become known at a later time and the man is a protected minority the article must be scrubbed of the negative stereotype.
