Honestly, there is never a reason to be rude, and people need to grow up and realize that being mean, in any terms, is just not acceptable. The world will become a much more pleasant place the day we can weed out unnecessary abuse towards each other.
All the people that say "don't be so soft (in ruder words generally)" have NO real logical reason for their abuse. It takes two seconds to realize that it's not about you as the abuser, but about how you make the other person feel, and whether it would affect you or not, WHY be mean? What is the benefit?
All the people saying this is a serious issue and needs to be stopped have no logical brain, venting helps mental health and strength, as does growing stronger against venting people, it takes 2 seconds to realise, this person will have no affect on your life past this point and that there is an ignore feature in the game.
Stay classy gd, don't dump on yourself by supporting this weasely whining brat.
