CRT definitions of 'White Supremacy' are not about 'people acting deliberately' to support it.
CRT laments that 'regular people' doing 'regular things' act unconsciously to support oppressive systems, hence 'White Supremacy'.
Making a film about 'something' and hiring those people you know to make it, who by virtue of your social network might be 'mostly white' - would be an example of 'White Supremacy'.
Ergo - in their view, unless you are actively fighting to dismantle the concept of whiteness - you're supporting 'White Supremacy'.
I believe there is a kernel of truth in systematic, even unconsciously biased systems, however, I don't remotely agree with many of the assertions. Unfortunately, to disagree with their assertions makes you a 'bad person' in their view.
Have a read [1]. A thesis of 'self examination' i.e. a fairly progressive individual addressing their own 'white supremacy' due to their lack of active assertion of issues of equity etc..
