Second, I thought I stated very clearly that I don’t align myself with any political party, so you can save the ‘”your "Friends, the D's"’ comment.
Also, the Civil war was not fought to end slavery or because so many people felt it was wrong. This is a popular misconception, but you have only to look at the facts to determine it’s untrue. The war was fought to preserve the Union. That is the reason those young people sacrificed their lives. The freeing of the slaves was a consequence of the war, not the reason for it. Lincoln himself stated that publically on several occasions. In his response to Horace Greeley’s editorial in the New York Tribune which had urged complete abolition of slavery, Lincoln wrote:
“My paramount object in this struggle is to save the Union, and is not either to save or to destroy slavery. If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that. What I do about slavery, and the colored race, I do because I believe it helps to save the Union; and what I forbear, I forbear because I do not believe it would help to save the Union.”
There was plenty of racism in the north at that time. It is absurd to think that a significant number of people would choose to die to help people they abhorred.
Based on your hypothetical scenario, you would think that a large number of minorities are being hired over whites. However, if you look at the ethnic make up of most large companies, I think you will find the vast majority of new hires, existing employees, upper level managers, and members of the Board of Directors are still white. The fact is, Affirmative Action has been dead at most large corporations for years. The official policy now is not to discriminate in hiring and promotion practices, but they are not to giving preference based on ethnicity.
However, I’m not sure this is germane to the topic of this thread. Nothing about hiring preferences was mentioned until you brought it up. This was about why minorities are not attracted to the Republican Party.
You are correct that most high ranking politicians in the south during the heyday of the KKK were Democrats. During that period, blacks overwhelmingly voted Republican. However, I think you also have to acknowledge that the base of both parties has changed significantly since then. After Truman desegregated the military, and the Democratic party included a Civil Rights plank in their platform, several of those top ranking southern Dems. (Dixiecrats) that supported segregation and Jim Crow split from the party. However, it was President Johnson’s signing of the Civil Rights Act in 1964 that caused the Dixiecrats to begin leaving the Democratic Party, and join the Republican Party to support Johnson’s opponent (Sen. Barry Goldwater), who opposed the Civil Rights Act. The first of the Dixiecrats to defect to the Republican Party was Strom Thurman, an avowed racist and segregationist. Other Dixiecrats followed. Then, there was the “Southern Strategy” first employed by Nixon, then later continued by Reagan & George H. W. Bush that pandered to southern Democratic voters that still supported “states rights,” segregation, and were anti-civil rights.
