A plan or program to accomplish a goal is a scheme, whether it’s beneficial or not.
Handing out flyers that properly define what socialism and communism are with the intent of educating people that they aren’t the boogeyman is still passing out propaganda, even if it’s beneficial and correct.
So yes, scheme is appropriate.
Armed minorities are harder to oppress.
Organized armed minorities make governments afraid.
Make no mistake, this is yet another message, “we do not care about you or your struggles”. Listen when they tell you they won’t protect you.
