Why should you be angry? They are just being stupid. Being stupid is something humans do naturally. Choosing to rely on someone who is verifiably stupid (in your opinion) is significantly worse, I think, than the original stupidity.

edit: And by the way, the very first time you are forbidden from patching a bucket you could patch yourself should be the red flag that tells you to use different buckets. Move on to better things and encourage others to do so too.
