Why idolize a socialist?

Why do conservatives idolize MLK just as much as the left does?  Conservatives consider "Capitalism is good" to be a "duh" statement, but MLK was clearly a free-enterprise-hating socialist.

Quotes:

 “The evils of capitalism are as real as the evils of militarism and evils of racism.”

“Again we have deluded ourselves into believing the myth that Capitalism grew and prospered out of the Protestant ethic of hard word and sacrifice. The fact is that Capitalism was build on the exploitation and suffering of black slaves and continues to thrive on the exploitation of the poor – both black and white, both here and abroad.”

 “The problems of racial injustice and economic injustice cannot be solved without a radical redistribution of political and economic power.”

And:

“I imagine you already know that I am much more socialistic in my economic theory than capitalistic… [Capitalism] started out with a noble and high motive… but like most human systems it fell victim to the very thing it was revolting against. So today capitalism has out-lived its usefulness.”

“And one day we must ask the question, ‘Why are there forty million poor people in America? And when you begin to ask that question, you are raising questions about the economic system, about a broader distribution of wealth.’ When you ask that question, you begin to question the capitalistic economy. And I’m simply saying that more and more, we’ve got to begin to ask questions about the whole society…”

“Capitalism forgets that life is social. And the kingdom of brotherhood is found neither in the thesis of communism nor the antithesis of capitalism, but in a higher synthesis.”

“Call it democracy, or call it democratic socialism, but there must be a better distribution of wealth within this country for all God’s children.”

“We must recognize that we can’t solve our problem now until there is a radical redistribution of economic and political power… this means a revolution of values and other things. We must see now that the evils of racism, economic exploitation and militarism are all tied together… you can’t really get rid of one without getting rid of the others… the whole structure of American life must be changed. America is a hypocritical nation and [we] must put [our] own house in order.”

“You can’t talk about solving the economic problem of the Negro without talking about billions of dollars. You can’t talk about ending the slums without first saying profit must be taken out of slums. You’re really tampering and getting on dangerous ground because you are messing with folk then. You are messing with captains of industry. Now this means that we are treading in difficult water, because it really means that we are saying that something is wrong with capitalism.”

“[W]e are saying that something is wrong … with capitalism…. There must be better distribution of wealth and maybe America must move toward a democratic socialism. Call it what you may, call it democracy, or call it democratic socialism, but there must be a better distribution of wealth within this country for all of God’s children.There must be a better distribution of wealth and maybe America must move toward a democratic socialism.”

“If America does not use her vast resources of wealth to end poverty and make it possible for all of God’s children to have the basic necessities of life, she too will go to hell.”
