I have noticed there are two types of blunt users here - are direct and polite, give honest opinion and actually try to help the asker - are direct and rude, try to bring the asker down and absolutely believe there perspective is higher.
We human beings are most times a confused lot. A lot of us out here don't realize when we are bullying someone and believe that what we are saying is correct & it's in good sense for the asker to accept it.
While yes there are those who are intentionally direct & rude :)
Yes, definitely. It is possible to be honest, yet kind as well. A person does not have to sugar coat everything they say but it's not hard to just re-phrase something or to say it in a different way in order to avoid causing drama and stepping on toes.
Some users are just mean and hide behind the excuse of "being blunt." It just causes drama because if someone is rude, it doesn't matter if they're being honest or not, the QA is not going to listen to them.
That being said, I have also seen some users complain of bullying where there isn't any. Sometimes people ARE just being a bit overly sensitive. It can be difficult to convey a point online when we obviously cannot hear the person's tone of voice. Sometimes people aren't being mean at all, the other person just takes it the wrong way.
