'Types' are just an instance of man made categories. Just another means for people to categorize things to make thinking and speaking about them easier. Like all other categories with varying degree of precission and success as a concept.
So it's real. Real man made categories.
So what?
Are they good categries? Depends on the context, for general observations: Sure. It's like nigger. Try to explain who stole the TV to police. Sure you can get it done by providing lengthy descriptions at the end of which your opposite finally understand you simply described what he categrized as 'nigger' and thus can exain in one word only.
