You are gullible, naive, paranoid and racist.
Point number 1: Republicans authored an amendment making slavery a constitutionally protected activity. The Republican party is the party of the Corwin Amendment that would have made slavery constitutional.
Point number 2: A Republican president, with the support of the Republican Party, ended reconstruction. The Republican Party is the party of the 1877 Compromise that ended reconstruction and paved the way for Jim Crow.
Point number 3: Once blacks got a foothold in the Republican party and gained some semblance of political equality, white Republicans took steps to purge blacks from leadership positions. The Republican Party is the party of the Lily White movement, a group of Republicans that worked to purge blacks from the party.
Point number 4: Republicans consistently broke promises or ignored issues that affected black people. When blacks got Civil Rights, the Republican Party did not believe that was civil or right and decided that extremism in defense of liberty was no vice. In 1964 the Republican Party turned its back on blacks after nearly 100 years of black support.
Point number 5: Today’s Republican Party is controlled by a racist Anti-Black base.
Understand that this is our experience with the republican party. Most blacks are independent. We vote for democrats because of their policies. The racist party, yours, that simultaneously opposes juneteenth, claiming it's pandering, or that tells us how we were not slaves while always telling us how we should vote for republicans because they freed the slaves will NEVER get the majority of black votes until the racists are removed from leadership and made irrelevant. All you hope to do is peel off enough blacks to gain power, your party doesn't give a damn about black people. Your party is the panderers.
