I find it deeply distasteful, that adult (usually) women are ganging up on little (usually) boys and hanging this massive label on them.
Do you know what I find distasteful? (among other things). Some of my behaviour when I was on my own, trying to manage a troubled little boy who had a will of iron, a vesuvian temper and no boundaries. When I 'ganged up' on him to get him to do stuff like, I dunno, not run into the road, or not freak out if he fell asleep out in the buggy and woke up in the house (cue 3 hour tantrum). That was very, very distasteful. I behaved in a distasteful way.
My son's DX has transformed my relationship with him. I absolutely get that people have anxieties around dx and of course, ultimately it is you and your family's decision to dx or not, but don't come on here and accuse me of ganging up on my beloved boy because I sought help and understanding for him. If you want to debate, kindly do so in measured terms.
To OP - It's really not a label, you don't have to share it, neither does your DC, unless it's helpful to you to do so. And it is infinitely more helpful than the other labels attached to HFA children - naughty, stupid, doesn't listen, withdrawn, precocious, too set in their own ways, etc etc etc.
