I watched a couple of them. Already seen several of these.
My question is, for whom are they doing these videos, and why? I speculate that they do it for themselves, to give themselves and others who know them the impression that they 'did something' to fix this shit. We have seen this before with Michelle Obama...
See that! I did something!
I think that is part of why there are so many of the selfie videos. They did something. They fought the system!
Of course an online video will make no difference. But they do not know or care about that. You cannot "wish" or "tantrum" reality into being real. They are learning this lesson, and it is hard for them to accept.
