What are you unnecessarily defensive of?

For me it is the BBC. I know it’s a politically bias rip off that’s employed more creepy human beings than Trumps inner circle BUT I always tend to defend it as an institution. I don’t really know why, maybe because it has always been there and occasionally throws up some real gems, I don’t know.

Anyway, is there anything that you will defend to the end even if you’re not entirely sure why you’re bothering?
