Liberals and leftists are not the same.

Liberals are what Malcolm X and Martin Luther King Jr. warned us about.

The White liberal is the worst enemy to America and the worst enemy to the Black man. Let me first explain what I mean by this White liberal. In America there’s no such thing as Democrats and Republicans anymore. That’s antiquated. In America you have liberals and conservatives. This is what the American political structure boils down to among Whites. The only people who are still living in the past and thinks in terms of “I’m a Democrat” or “I’m a Republican” is the American Negro. He’s the one who runs around bragging about party affiliation and he’s the one who sticks to the Democrat or sticks to the Republican, but White people in America are divided into two groups, liberals and Republicans…or rather, liberals and conservatives. And when you find White people vote in the political picture, they’re not divided in terms of Democrats and Republicans, they’re divided consistently as conservatives and as liberal. The Democrats who are conservative vote with Republicans who are conservative. Democrats who are liberals vote with Republicans who are liberals. You find this in Washington, DC. Now the White liberals aren’t White people who are for independence, who are liberal, who are moral, who are ethical in their thinking, they are just a faction of White people who are jockeying for power the same as the White conservatives are a faction of White people who are jockeying for power. Now they are fighting each other for booty, for power, for prestige and the one who is the football in the game is the Negro. Twenty million Black people in this country are a political football, a political pawn an economic football, an economic pawn, a social football, a social pawn... -- Malcolm X

I must confess that over the past few years I have been gravely disappointed with the white moderate. I have almost reached the regrettable conclusion that the Negro's great stumbling block in his stride toward freedom is not the White Citizen's Counciler or the Ku Klux Klanner, but the white moderate, who is more devoted to "order" than to justice; who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice; who constantly says: "I agree with you in the goal you seek, but I cannot agree with your methods of direct action"; who paternalistically believes he can set the timetable for another man's freedom; who lives by a mythical concept of time and who constantly advises the Negro to wait for a "more convenient season." Shallow understanding from people of good will is more frustrating than absolute misunderstanding from people of ill will. Lukewarm acceptance is much more bewildering than outright rejection. -- Martin Luther King Jr., Letter from the Birmingham Jail
