Good men don't victim shame. Your father (and many, many others) chose to ignore 100% proof of something false yet to still characterize it as the "truth".
My question to you is: Do you think it is possible that you might have inherited a similar illogical approach to life?
My Father, like most people, likely assumed others thought/felt they way he did. He probably was somewhat surprised/disappointed others took it all so seriously. His choice was 'logical' just like yours seems to be to you. Up till now you have been inoffensive, don't change that by attacking the character of others you didn't know.
