That kinship issue is one of the reasons the sane and reasonable NCSU fans should be very forceful in policing the insane and unreasonable NCSU fans. When you fail to do that, it is only natural that we see all of you as trash and/or insane freaks.
I grew up in SEC country with family members on all sides, including the wife's, that are SEC people of various schools. I know monomaniacal obsession by fans that leads to pure insanity. Nothing in the SEC is any worse than NCSU fans.
Instead of lecturing us, perhaps you should try to clean up your fellows and help them become grounded.
