I don't know what Fromm said that you believe has been "proven" false, but I'm sure I wouldn't accept your explanation. Listen, in the end, the only thing that matters to me is what I believe to be true, based on my experience and reason. And if someone has conflicting convictions, to the point that I find their values in conflict with my well being, then eliminating that threat by any means necessary is perfectly acceptable. That is how life works, it is bigger than the human species, and I don't need to provide any references. Fuck it
