Can a stereotype ever be a good thing?

in some cases even "good" stereotypes cant be good ones

This is only my opinion but I beleive that any type of steryotyping is bad. I don't think that people should generalize a certain idea or a certain group of people because everyone is different in their own way. So basically what I'm trying to say is that steryotyping can't really ever be a good thing.  And again this is a pretty debatable topic because some people think it can be a good thing sometimes, but I honestly in my opinion think it offends people. It just depends on the way you look at it.
