Substitute 'Argument' for 'Debate' Mark and yes I am. Of course people have different opinions on it but one thing that seems fairly certain is that many people do have problems with internet 'banter' that is taken too far, same as people in everyday life do.
As Sarz has pointed out, many people have severe mental issues with this and it needs attention, they are the victims, but what about the abusers? what kind of person is it who can knowingly and regularly insult and mock others without their conscience bothering them, especially when the person on the receiving end is complaining about it? telling them to "get out of the kitchen" doesn't cut it, and it's made worse when the whole gang jump in, these are the guys who need to have a look in a mirror.
