Why do people say they listen to anything but Country?

It irks me when I hear someone say "Oh I listen to anything but.." country is usualy what they say. But there is so much great Country Music- and its so diverse and a big Genre . Legends like Patsy Cline, Johnny Cash, Marty Robbins, Willie Nelson, and others paved the way for many Rock and Roll artists and Pop stars that followed. And- there is so many different styles of Country- its not just one thing. But most people think its just one thing. It seems like they aren't true music lovers if they dont appreciate it. Im a music lover and I love ALL MUSIC- including Country. Especially Clic Country and Western.
