Chastised their teammate/s that kneeled, in public.
Chastising their teammate/s in secrecy is cowardly.
Since the kneeling was done in public the chastisement, for it to carry any weight, should also be done in public.
And you still might not know.
If they stay on the team, how much beat-down do you expect there to be “in public”?
I’m not going to hate on these people just because they try to hold their peace. It has to be a hard choice for many.
