The Republican party doesn't want to coddle minorities because it believes that minorities are just as capable as the majority, and believes that introducing dependence perpetuates problems. The Democrats want to keep dependency going because they get to harvest votes (instead of the cotton they used to get). Yes, this is surprising news to you that the *Republicans* believe in true equality regardless of race - but that is the history if you care to look.
The sad thing is that I think you've actually convinced yourself of that. That the political parties are now as they have always been, and that the Republicans are still the "Party of Lincoln."
No, if you really look at the history, you see people like Strom Thurmond and his fellow Dixiecrats who left the Democratic Party to become Republicans in the wake of the 1964 Civil Rights Act. You see Nixon and the Southern strategy. As Kevin Phillips, Nixon's political strategist said at the time:
"From now on, the Republicans are never going to get more than 10 to 20 percent of the Negro vote and they don't need any more than that...but Republicans would be shortsighted if they weakened enforcement of the Voting Rights Act. The more Negroes who register as Democrats in the South, the sooner the Negrophobe whites will quit the Democrats and become Republicans. That's where the votes are. Without that prodding from the blacks, the whites will backslide into their old comfortable arrangement with the local Democrats."
The mid 20th century was a transition time in which the Democrats split over the issue of segregation v. equality. Thurmond's Dixiecrats feuded with the rising liberalism in the party, and the end result was that most Southern Democrats were replaced with equally racist Southern Republicans -- at least the ones that didn't just switch parties themselves. It would be the Republican party that would squeeze out its pro-equality members over the next few decades, not the Democrats. As LBJ is said to have told an aide upon signing the Civil Rights Act, ""We have lost the South for a generation." It was the Democrats who made the political sacrifice to do what's right on race. And it was the Republicans who made the cold, amoral decision to pander to racists to gain their votes.
Although it was then-Democrat George Wallace who first linked popularized the connection between racist policies and states rights, it was Republican Barry Goldwater who ran with the idea and became the first Republican candidate to win the South with Reconstruction. Nixon's subsequent campaign on "states rights" and "law and order," all under the guidance of Harry S. Dent, was well understood by Southerners to mean support for racially biased policies. As Lee Atwater said:
"You start out in 1954 by saying, 'Nigger, nigger, nigger.' By 1968 you can't say 'nigger' -- that hurts you. Backfires. So you say stuff like forced busing, states' rights and all that stuff. You're getting so abstract now [that] you're talking about cutting taxes, and all these things you're talking about are totally economic things and a byproduct of them is [that] blacks get hurt worse than whites. And subconsciously maybe that is part of it. I'm not saying that. But I'm saying that if it is getting that abstract, and that coded, that we are doing away with the racial problem one way or the other. You follow me â" because obviously sitting around saying, 'We want to cut this,' is much more abstract than even the busing thing, and a hell of a lot more abstract than 'Nigger, nigger.'"
The only reason Republicans pretend to care today is because the political landscape has changed, and the failure of Mitt Romney to defeat Barack Obama because of half a century of burning their bridges with blacks and a quarter of a century of doing so with Hispanics, combined with shifting racial demographics as whites are on schedule to no longer be a majority means that appealing only to whites is political suicide.
This isn't principles or long held beliefs in true equality. This is nothing more but the same cold, amoral calculation that it's no longer Kevin Phillips' era, and if you want to know why it's falling on deaf ears, it's because minorities in this country have spend so long hearing "dependence" and "personal responsibility" and "47 percent" and knowing that what the speaker really means is, "Nigger, nigger."
