NO. There is a HUGE difference between questioning what I say, which is perfectly fair, and insulting me personally.
If I say something controversial, BY ALL MEANS challenge what I say. BY ALL MEANS, disagree with me.
But mock me personally? Ridicule me personally? That is not the reaction of an adult.
Places like this bring out our worst behaviors. People say and do hurtful, destructive things that they would never do (one would hope) in the real world.
IT IS WRONG, UNCONDITIONALLY, to attack someone personally because they state a premise with which you disagree.
