Facts can't win if emotions are involved. Facts only work when everyone is rational, but, to quote former FBI hostage negotiator, Chris Voss, from his excellent book on negotiation (Never Split the Difference): humans are inherently irrational. A large chunk of his book is how you rarely succeed in arguments or negotiations based on facts, because humans are irrational emotional creatures. I highly highly recommend reading the book (because its great, not because it says this particular thing).
