I've met Davros twice (I think):
Once when I hosted a Guardian Live event about his book in 2014.
Another time I interviewed him for The Big Issue when I was guest editing in 2015.
He also gave my publishers an endorsement for my book, which I was mortified about at the time mostly because I thought it was so OTT it would obviously invite ridicule (which it did).
At the time I saw him as a crude means to reach disillusioned younger people - the sort of people who wouldn't be reached by conventional journalists and politicians advocating for the policy of exterminating all humans and becoming the supreme power of the universe .
As a result I was willing to overlook, or just not look into, his history of problematic behaviour / statements, including sexism towards Sarah Jane Smith and Romana.
