Please get some help, this is not how people behave as a community.
The rest of us do not always agree, but the general rule is that we all rub along, accepting our differences.
We may be the playground, but think on this, IF we are, then where would you be, alone in a corner, because no one in real life can put up with such behaviour.
As adults it is the same in say a pub, people won't put up with it, unless they have known the person previously and know that they are not 'their usual self' and I would hope that friends and family would direct them to get some help.
So playground folks, just get on with being well rounded human beings, having a bit of fun along the way, because life wouldn't be worth living without a smile and a bit of a laugh.
