Yes, exactly what are they “locking arms” about? It isn’t clear at all to me.
I don’t get the feeling that they are locking arms in unified support/respect for the flag and the national anthem.
The “locking arms” is just a watered down version of kneeling. They want to kneel, but they have to lock arms because they know they’d get too much grief for kneeling.
Just like kneeling before the anthem instead of during it. It’s just a p*ssy version of kneeling.
