And why is finger-pointing bad? If someone farks up, you SHOULD point and say they farked up.
But that is only one part of trying to solve the problem. Analyse the problem and find an improvement. You cannot fully analyse anything if you exclude parts.
It becomes a problem when people attack each other personally. 'Bob, the job you did was poor' is vastly different then 'Bob, are you to stupid?'
F.i. If the person that farked up did so out of being incompetent, well then replace the person.
Why should you act otherwise? This is not kindergarten where no one wants their feelings hurt and everyone gets a medal. This is Real Life Grownup Stuff and if you are paid to do a job, you do it good or face the consequences.
We do not all have to agree on anything, as long as we all work together for the betterment of the community. (Quote by someone, can't remember)
Sad fact is, these people are not doing such and thus it is the moral obligation to call them out on such.
People only cry foul play when they find themselves the target.
