Clutch Pedal/linkage problems of the 2005 Subaru Impreza Wrx

Under normal city driving and highway commuting the transmission and clutch pedal stopped delivering power on the highway. I managed to safely get off the highway and had the car towed to dealership. Dealer refused to cover worn clutch under warranty despite wear items covered under the 3 year//36000 mile coverage. Car was around 20000 miles. Dealer gave me a feeling that I was discriminated against because I was a young man with a sporty car, therefore, I must race it and abuse it. I have old parts in my garage. They did, however, cover brake pads at another time.
