The issue is that you've shown up for what was otherwise actually a reasonably civil conversation about slavery, it's legacy, the legacy of various prominent individuals involved in US slavery, and various moral positions associated; and all you've done is accuse others racism and intellectual dishonesty because they disagreed with you or asked you to clarify or refine your position.
In short: you showed up and took a great big **** on this thread, and all of it's participants.
It's not that you showed up for a knife fight with a knife rather than a pen; it's that you showed up for a civil discussion with vitriol, obtuseness, and othering.
