What's with the hate on long nails?

I have natural long nails and can't stand short ones. On guys they are ok but on girls it make you look manly and gross. No matter what if you nails are short I think they bite them which is nasty. I take a lot of time taking care of my nails and love them long, and other people do too (so I can scratch their backs). They are also useful weapons. You piss me off and I wil scratch or dig my nails into you.
