You didn't say anything really -- you just posted something from a website that said "maybe" they were or weren't "offensive" or "problematic" and I responded that "maybe" they were just following in the footsteps of the man whose hat they were all wearing.
The video is there for all to see and to judge accordingly: if you want to make the argument that "maybe" how those kids were behaving in said video shouldn't be an issue, then -- as usual -- I don't see much point in trying to convince you otherwise.
