Why does it feel as if SOME (not naming any names

) stanbases cannot accept any criticism whatsoever? If someone makes a light-hearted joke about my faves I'm not too bothered, it's really not a big deal. However, some other people are VERY WP trigger-happy and have some bizarre notion that every little thing is an attack towards their fave and it's their duty 24/7 to protect and worship them. It's quite annoying to be honest.
So, do you think you take criticism well?
What do you do when someone shades your fave?
