Thing is, as with any forum, I can only see the words on the screen and respond to them.
I can't see body language, I can't hear tone, so a large part of communication is lost. I only have the facts/feelings which are laid out in front of me. There's no way I can compensate for the whole range of emotions which might lie behind that post so I'll respond to what I can see.
Also this is a fast-paced forum with no edit function. People type, post, and then think at least 50% of the time. I've done it myself - posted something and then though 'fucking hell that was a bit forthright'.
Some responses on this thread are tongue in cheek, but if you read them black and white then they look harsh and bullying. Take it all with a pinch of salt and avoid the areas which draw the contraversial argumentative types. If I'm feeling irrationally pissed off and looking for a fight I know I can usually find a good one in AIBU 
MN has a reputation for saying it like it is and it lives up to it. Don't want your baby name choice criticised? Don't ask for honest opinions then. If I think your proposed name is chavvy, or overused, or every small Morticia I've ever known has been a horrible child then I'll tell you that name doesn't do it for me and I'll tell you why. In RL I'll grit my teeth and say 'Loocie-Mortisha-Mai, what a lovely name and such innovative spelling!'. Here I'm going to tell you that 3 names is at least 1 too many, don't try to be clever with all different spellings because your child will hate you and every small Morticia I've ever known has been horrible.
