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.
As someone without allergies that has been around for too many peanut-related reactions, I absolutely hate that this article exists.
Too many times I have heard people be dismissive of a person's severe peanut allergy, to the point of thinking it's funny to bring a peanut butter sandwich to work and wave it in someone's face, and then get defensive when it triggered a skin rash from proximity alone.
I've seen people put peanut butter on an allergic person's car door handle.
I've seen people put peanuts in someone's food "because they have to be faking it"
The reason I hate this article is because it will encourage too many people who "have done their own research" to put peanuts in things "to help build up a tolerance"
Someone is going to die from that "studies suggest".
And I really am tired of hearing "you're overreacting, that's not going to happen" given the current state of the world.
