Kids are starting to do it at their games, and schools say they have the right to do so.
You're right - We are just witnessing the tip of the iceberg of this garbage. Colleges, High Schools, Junior High and Pee Wee teams will now emulate their "heros". Some have already started. They believe it's the IN thing to do and cool.
I'm glad my boys are grown and older men now, and not faced with this coming garbage.
