It comes in cycles. The fact you don't see it a lot tells you that it doesn't happen often. Some of us have also put a lot of effort in trying to convince those that do it that it truly is not a beneficial thing. We've managed to change some minds, and some attitudes. It wasn't easy. There is no big red easy button we can slap to make it go away. :)
The fact you don't see it much is I think a testament to how truly wonderful this place is. I don't believe pretending these issues do not exist is a good thing either. I'd rather acknowledge problems and try to come up with a positive way to try to approach and deal with them.
I think that's certainly the best way to deal.
