It is normal play for boys.
The type of wrestling she's talking about is NOT normal play -- it may be commonly accepted in today's society, but that doesn't make it normal nor advisable.
Pro wrestling is scripted violence tailored to soak up money from adults. Many kids have been very seriously injured trying to emulate what they see on those shows.
Yes, boys need an outlet for their energy. Playing real sports, either pick-up games with friends or in organized leagues, is much better for them than exposure to or participating in gratuitous violence.
OK thanks. I never watch that stuff. Remember when there was nothing on TV when we were small except for wrestling? I hated it then and would never watch it now- but I have heard it is scripted violence.
