So even though it upset your daughter, you'd happily do it again, not only risking upsetting her again, but giving her the impression if something doesn't go your way, stomp your feet and cause a scene.
I have not insulted anyone's mental health, I posted a link that I found on Anger Management techniques. Show me where I insulted anyone's mental health. You can't because it didn't happen.
I acknowledge my replies haven't been sparkled with roses and fairy dust, but OP after all this, after upsetting her daughter, has said she'd happily do it again. As others do, I believe what was posted and what happened are few and far between. Unfortunately making it juicier didn't go in OP's favour.
I'm annoyed as you shouldn't behave like that in front of DC, full stop, especially if it upset them. I believe assertions were made about this guy, when she knows nothing about him. Her general demeanour through the post has been just 
on a topic any hardened MN knows will stir controversy.
She posted on NM & MN presumably getting the same or a similar response, yet we're in the wrong for not agreeing with her on this. Since we don't agree we're bullies.
Since its apparent OP has learned little from the experience, I won't be returning. FYI accusing people of what they haven't done, especially when they were trying to help is aggravating. OP knows this though and seems to enjoy provoking others. A means to an end, whether it be a car park, MN or NM.
You can't reason with stupid.
Have a good day.
