Do we really need the tomboy category?

This "tomboy" trend is becoming increasingly popular in Asian cultures. What is your opinion on this? I believe last thing we need is another category based on looks. we're already overwhelming with the "butch, the fem, the emo, etc." Now lots of girls think dressing up like a boy is a cool so they start doing it. why can't people just be naturally butch? like naturally masculine (naturally as in on your own will kind of). if you go on youtube there's tons of videos of "tomboy stars" and fans going "that style is cute, i should try that too" since when was a tomboy a style? this is ridiculous. I wish people would stop categorizing them self.
