I can think of numerous minority Republicans. They do not discriminate against minorities. Some FACTS about Republicans and Democrats:
1. Republicans fought to abolish slavery and Lincoln was the first Republican president.
True. The liberal Republican party of the day was anti-slavery. At least in the north. Strangely enough, so was the Democratic party of the day. The early division of pro-/anti-slavery sentiments correlated strongly with the 'north'/'south' divide. Not so much with the Republican/Democrat divide.
2. Democrats fought for slavery.
As did Republicans. (See point 1). More congressional Democrats voted for the Civil Rights Act than did Republicans.
3. The KKK was a wing of the Democratic Party. Segregation and Jim Crowe laws were supported by Democrats.
The KKK was a terrorist organization, not a 'wing' of any political party. Segregation and Jim Crow laws were supported by *southern* Democrats (aka: 'Dixiecrats'), not by Democrats in general. Strangely enough, when the Democratic party (dominated by the voices from the North who were *against* those things) metaphorically kicked those Dixiecrats to the curb, they fled to the Republican party, and took their (largely white and racist) voting base with them.
5. The civil rights movement was started by the Republican Party and the civil rights amendments were passed with a greater percentage of Republican votes than Democrat votes.
More Democrats voted in favor of the Civil Rights amendments than did Republicans.
6. The notion that the two parties "flipped" at some point is a myth started by Lyndon Johnson as part of what he dubbed the great "Democratic Delusion" in an attempt to make progressive values Democrat as a means to power.
The parties *did* flip. The Republicans *used* to be the liberal party of this country. They haven't been since shortly after the Republican party adopted its 'Southern Strategy'. This is well documented: https://en.wikipedia.org/wiki/Southern_strategy
7. Entitlements and other government programs are designed to keep poor beholden to the government and in favor of it. Democrats don't want people to get a leg up and help themselves. By design it is a means of control.
Let me get this straight, you're in favor of giving people 'a leg up', but you're against things like welfare which *actually do that*?
The current (conservative) Republican idea of 'a leg up' can be boiled down to a sentiment of, "**** you. I've got mine, you can eat **** and starve. Get a job, you lazy bum!" as opposed to the current Democratic idea of 'a leg up', which is "Crap, you've got it tough. Let me help make sure you and your kids have food and shelter and the tools necessary for you to find a job."
Get some real information and don't believe the lies or go spreading misinformation about a political party.
You should take your own advice. You repeatedly conflate the southern Democratic contingent (the Dixiecrats) with the entire democratic party. The schism between the two started back in the late '40s, well before the Civil Rights movement got any discernible momentum (1954-1968). Even before 1948, when the Democratic party officially adopted civil rights as a plank int he party platform, they were effectively separate parties. Nothing more than inertia kept them together under the 'Democrat' label by that point. This is similar to the GOP/TEA Party issue of today. They aren't the same party, but the TEA Party formed from a subset of the Republican party and they can't bring themselves to formally split off because they know that if they do, they'll lose a lot of the power (and votes) associated with the 'Republican' name.
