"So then you agree that your statement about no blacks being allowed to vote in the north was incorrect."
With that in mind, I invite you to show me where I ever said that *NO* blacks were allowed to vote before the Civil War.
If you cannot, then I must conclude that (1) your original statement above was incorrect at the time it was made and (2) you are now lying about making that statement by suggesting that it was either never made or has been misrepresented.
