I'm surprised our paths haven't crossed yet here on FR. Your login name intrigues me since I was a member back in the early 1960's of an equally evil outfit, the NAACP!
As a naive (idiotic, to be honest) college student, I was a dues-paying, card-carrying member of that racist, thoroughly Marxist scam. Although I regret every cent I paid in dues to the NAACP, it was an eye-opening experience for me since I saw the reality of this radical hate-filled group. I would surmise your experience with the ACLU was not too different from mine?
Fortunately after that brief detour into leftism, I returned to my Conservative roots after transferring to a Christian college. Thereafter, I worked enthusiastically for Barry Goldwater in 1964 and have never faltered in my Christian walk nor my unabashed Conservatism.
The American Civil Liberties Union is a fierce enemy of many civil liberties, it is sad to say.
