How old am I?

I'm so old that I remember when one of the most sacred dogmas of liberalism was that segregation based on skin color was of the Devil, was Nazi, was born of the very pits of Hell:

Which is why it's being embraced by the modern Left.  To understand the 21st Century Left take everything postwar liberalism said was evil and demand it be called good, and take all that postwar liberalism said was good and righteous and condemn it as evil. Easy peasy, Japanesey*.

*Since liberals used to condemn such a phrase as racist I'll assume we must use this phrase repeatedly to avoid being called a racist by the Left today.
