Neither of these is a small niche. Police brutality is a huge, huge issue. It may seem like a small niche to people who are not members of targeted demographics, though.

What leads you to believe this? From my personal experience this couldn't be more wrong
Anyway, if you want real counter culture that middle aged people will still clutch their pearls over... what about Antifa?
I'm not saying it's not important -- but as a request for change it is niche in scope, that is constrained to a small area of life (even if you are one of the targeted demographics).
>What leads you to believe this?*
Well, some internet ranting and rare protesting aside I don't see any alternative lifestyles there (or only very trite ones, the "fair trade coffee" equivalent of politics). It's all business as usual otherwise.

Better in the shocks middle aged people respect, but scores less points on "culture". It's a reaction-based group, not an alternative cultural force.
To argue, as BLM does, that we should restructure the entire policing system (some say even dismantle it) is to conduct a reimagining of what power and authority means in this country.
In a place where "law and order" (one of Trump's favorite phrases) and the administration of "justice" is upheld as the highest ideal, to decisively argue against normative ideas of them is certainly counter culture.
Also antifa is not reactionary. Many members of antifa orgs run community kitchens, organize reading groups, or build small farms or communes.
The specter of police violence is not constrained to a small area of life for members of targeted demographics....
If tame middle aged people who listen to Enya and mass media outlets can root for your cause, you're not exactly a counter-culture.
