The founder of the ACLU's stated goal was the destruction of the USA. So this is not surprising.
For one there are multiple founders but I assume you're referring to Rodger Baldwin rather than that subversive commie Helen Keller.
Second, he didn't call for the destruction of the USA, you're simply lying and we know that's par for the course.
I believe this is the quote you or something you read sometime was referring to:
I am for socialism, disarmament, and, ultimately, for abolishing the state itself... I seek the social ownership of property, the abolition of the propertied class, and the sole control of those who produce wealth. Communism is the goal.
Sounds harsh, but he's not calling for the destruction of the United States and if you remove the Socialism and Communism references he sounds like plenty of the wingnuts on this board who have called for open rebellion and the dismantling of our government.
For the record, I disagree with Roger Baldwin on the quote above but thankfully there are more quotes which begin to paint a broader more complex person such as:
I regard the principle of conscription of life as a flat contradiction of all our cherished ideals of individual freedom, democratic liberty and Christian teaching.
Watch out that commie also likes democracy and Christianity. Time to attack the baby Jesus. Another quote:
So long as we have enough people in this country willing to fight for their rights, we'll be called a democracy.
And another...
would say that social work began in my mind in the Unitarian Church when I was ten or twelve years old, and I started to do things that I thought would help other people.
Another...
The rule of law in place of force, always basic to my thinking, now takes on a new relevance in a world where, if war is to go, only law can replace it.
However in the end the guy is dead and the ACLU has a history of defending the rights of others regardless of their own political ideologies like Rush Limbaugh and the KKK both of whom are staunchly right wing.
So, **** off with your lyin' self.
