To understand the viewpoint: think of the products you feel like you justifiably have to buy that support evil corporations that also donate to political orgs that go against rights. A $20 book (or <$70 box set) costs less than the amount of money most people put towards buying Coca-Cola products. And this can be difficult to change when you're used to certain products, especially if you don't know about the trouble from their corporations/parent corps/etc.

The banality of evil, yo. Our society has structural problems and people can't pay attention to all of it.
