Your version of Coolidge's history on race is completely ahistorical.
The quote you posted traces back to a dubious blog, which neither cites nor explains where exactly the information comes from. Coolidge is actually notable for speaking out against anti-black racism, supporting legislation to bring an end to lynching, and helping restore rights to Native Americans. Suffice it to say, you're completely full of shit and it was a terrible idea to try and engage me on a conversation about history.
An actual quote from the man, taken from a letter he sent to Charles Gardner: "Leaving out of consideration the manifest impropriety of the President intruding himself in a local contest for nomination, I was amazed to receive such a letter.
During the war 500,000 colored men and boys were called up under the draft, not one of whom sought to evade it. They took their places wherever assigned in defense of the nation of which they are just as truly citizens as are any others. The suggestion of denying any measure of their full political rights to such a great group of our population as the colored people is one which, however it might be received in some other quarters, could not possibly be permitted by one who feels a responsibility for living up to the traditions and maintaining the principles of the Republican Party. Our Constitution guarantees equal rights to all our citizens, without discrimination on account of race or color. I have taken my oath to support that Constitution. It is the source of your rights and my rights. I propose to regard it, and administer it, as the source of the rights of all the people, whatever their belief or race."
What any of that has to do with Cyborg and her barbaric behavior, I have no idea.
