There should be a "Liberal Appreciation Day" celebrated in this country considering what they have brought to America.
The very definition of "Conservative" is "fear of change". I have no doubt that without liberals, we would be theocratic English colonies with slaves.
And look at our history of Literature, Theater, Dance, Music and the other arts. The history of Art in America is almost the History of Gays. So much from such a small group of people. Look at how much America owes Alan Turing and he wasn't even American.
Our greatest institutions of higher learning, research and technology are mostly in Blue States for a reason.
Weekends, 40 hour work week, child labor laws, vacations, health care, equal pay for equal work, and all the other benefits workers get were never supported by conservatives. These have always been seen as "liberal".
And when you look at the enormous diversity within Liberals as a group, they will be a strong force far into the future. Blacks, Hispanics, Whites, gays, atheists, religious, rich, poor, scientists, teachers, straights and so on.
We really should have a "Liberal Appreciation Day". To thank Liberals for what they brought to this country in spite of so much opposition.
