Republicans lionize him because they got nobody else. Teddy Roosevelt and Ike would be called communists by teabaggers today, and they'd rather forget about Hoover, Nixon, Bush 1 and George W.
As for black people...
*Reagan kicked off his 1980 campaign in
Philadelphia, Miss., which at the time was known for only one thing: the Ku Klux Klan murder of three civil rights workers. Reagan, using the code words of the day, said, “I believe in states rights.” (just like George Wallace, Orval Faubus and other white southern politicians before him)
*Reagan was opposed to the landmark
Civil Rights Act of 1964 (a referendum on Jim Crow).
*He was also opposed to the
Fair Housing Act, saying: "“If an individual wants to discriminate against Negroes or others in selling or renting his house, he has a right to do so.”
*As president, he actually tried to weaken the
Voting Rights Act of 1965 (he called it a great insult to the South).
*He tried to veto the
Civil Rights Restoration Act passed by Congress to overturn a Supreme Court ruling (Grove City v. Bell) that limited the remedies available to the federal government when going after private organizations that receive federal subsidies. The democratic-led Congress overrode Reagan’s veto.
*He tried to get rid of the federal ban on tax exemptions for private schools that practiced racial discrimination (
Bob Jones University). Congress blocked it.
*In 1988, he opposed a bill to expand the reach of
federal civil rights legislation. The democratic Congress overrode the veto.
*Reagan also opposed the imposition of sanctions on the
apartheid regime in South Africa. The Democratic Congress overrode that veto, too.
After one of Reagan's pro-apartheid speeches, the normally mild-mannered Bishop Desmond Tutu said: “I found it quite nauseating. I think the West can go to hell…Your president is the pits as far as blacks are concerned. He sits there like the great, big white chief of old.”
*He referenced to black women as
"Cadillac-driving welfare queens" (nevermind that most welfare recipients are white)
*When
MLK was murdered, he argued that he had it coming. Reagan said it was just the sort of “great tragedy that began when we began compromising with law and order, and people started choosing which laws they’d break.”
*He opposed the
MLK holiday: When John Conyers introduced the bill with the backing of the NAACP, Reagan vowed to veto it.
He only signed it after the democratic Congress passed the law with a veto-proof majority. All 22 senators who opposed it were republicans.
Reagan signed the law grudgingly, noting he did so because “Congress seemed bent on making it a national holiday.”
Black people didn't hate him by accident. He was a racist, plain and simple.

He also held up funding for
AIDS research for 3 years after it was initially described as a "gay disease" by Jerry Falwell and the Christian right.
