How to treat the young man grabbing the basketball court and punching the square dance grandfather?

1 First of all, let's take a look at this title: "The young man dances in square dance and fights with grandpa to grab the basketball court". I think the person who started this title came to rub the heat. At that time, he didn't even watch the video (not didn't watch it), or he came to mislead us people who eat melons.

2. Did the young man in the video fight back? I stopped when I was hit by a group, and then I pushed it.

Basketball court, the first function is for people to play basketball, followed by parking, dancing and walking. Square dance, literally, can be danced anywhere. Is it appropriate to forcibly change the function of the venue when you are old? What is the difference between this and forcibly changing educational land into industrial land? )
