Yeah, this is a really good point IMO (who said we couldn't agree from time to time?)Honestly, all for more involvement. But quotas reek at impatience at something that won't and hasn't healed in just a generation.
The temporal aspect of things like this is one that I don't think often is properly factored into responses to past oppression/experience -- cutting across all the various social campaigns undertaken by the Left (insofar as 'the Left' is an amorphous blob who all undertake the same campaigns in the same ways). There's a sense that, if everyone thought like I do/the state does what I think it should do, that centuries, if not millennia, of oppression based on ***uality, gender or race can be unwound. But overnight, magic bullet solutions don't exist.
The quotas here, while ostensibly well-intentioned, do strike me as an attempt to solve what is a long-term problem in a far-too-short period of time. So it's no surprise that they lack any real efficacy in producing deep, institutional change.
