I hate mentalities like this because it excuses the horrible and never justifiable behavior of previous generations. I do not care if as a society discrimination against people of color, immigrants, the mentally ill, and lgbtq+ individuals was normal, it is still unacceptable and horrible. I get it. I really do. There will always be a stark disconnect because it truly was a different time. But it sounds like an excuse to me.
Also, I want to say I'm not giving Walt Disney, or even Disney as a whole a pass. They made some racist ass animations back in the day and Walt's associations were dubious. I guess the difference between them is, there was more to Walt Disney than the racism and supposed "Hitler associations". Doesn't really change anything, but you know. it's there.
