Why do you think it is pure madness for Ursula to question the holocaust narrative? It's only seen as madness thanks to a 70 year propaganda campaign that has led to the situation where people like Ursula can be imprisoned for her views. Once you start looking into the dynamics that led to the events it naturally leads to questions about the events themselves. The dismissal of those asking questions as 'deniers' or 'anti-semites' or labelling their views as pure madness is the problem in my opinion and until more people actually start looking into the events for themselves rather than dismissing anything and everything that disagrees in any way with the accepted narrative we are doomed.
