Your friend is not harmless. Spreading QAnon bullsh*t is evil.
She has been a good and generous friend. I actually know little about QAnon BS. I assume it has to do with right-wing extremist conspiracy theories. She has never gone down that route. She is into magical healing stuff but that is all.
Right-wing extremist - any form of extremism actually - has been successfully using naive people to spread their messages of hate. Your friend needs to be made aware that "QAnon" is not only bullshit but crazy bullshit.
