One day someone will out of the blue relife his stress on you totaly undeserved and u wont even be able to judge that person as you just done the same. No matter if in private life or worklife.
Moral Apostel here but nonetheless its achiveing nothing, actualy just usualy the opposit of what you want. If 10.000 people run over me because of something that im pissed off about myself i wouldnt care anymore either way and say both sides can go fuck themselfs, im moving onwards to something else, let them see how far they can get alone.
And thats just one aspect of negative influences it has.
Im not saying that giving your neutral opinion is wrong though. Repeating over 10.000 times that we want a change in a proper manner is at least trying to achive something, all without raging or even insulting the one you depend on.
