Another issue with the written word, such as in these forums, is that emotion can not always be shown. For example, I could say something jokingly, and meant to be taken lightly, but depending on how I type it...it could come across to others as being mean or negative.
Sometimes people read things the wrong way, and instead of trying to understand it they immediately go on the attack.
Very true, easy to get caught up in the moment and respond before thinking about what the poster was trying to say.
