The irony of journalists describing/alluding to Trump's supporters as "drinking the kool aid" is that most of the people who died at Jonestown via poisoned drink were black.
I think this is a failure both in how we understand Jonestown (forced suicide) and the activeness of white complicity in racial supremacy (you might be sold false and racism-exploiting promises by a politician, but you are certainly not "duped" into being a racist)
Re: the blackness of Jonestown and the People's Temple (which gets into some very good political history about the blackness of San Francisco), I've learnt so much from @jamilahking https://www.motherjones.com/politics/2018/11/jonestowns-victims-have-a-lesson-to-teach-us-so-i-listened-peoples-temple-anniversary-40/
