I think it would do good to just internalize what's happening - the desire for personal gain, and the indifference on the ways that are employed. There is no shame in not caring about other people on a societal level, I don't think most of us do, and I do think that many who say they do, don't really actually. Calling them names like stupid or gullible, just to defend contributing to the harm of them is not successful coping attempt however. It just says that these things do bother who's saying them, and that they feel something that's not desirable to them, like shame, or fear of retribution, or something else that's negative. There's no need to do any of this, it's okay to just not care.
