“and they are wise enough not to feed into”
So the plan is to continue not responding and hoping it will just go away. Basically, respond with apathy.
This has been the plan over the last four decades of them calling the Founders racist. What exactly recommends this plan to you now as a good plan for the next four decades going forward?
The plan is to not be stupid enough to get drawn into arguments over the morality of slavery thinking that you will magically exempt the Founders.
The Founders who owned slaves aren’t going to be granted an exemption.
The Left are going to call the Founders racist no matter what anyone else says. It’s what they do. Dimwits like Dinesh and Beck think it’s a great idea to battle the Left on the ground of their choosing.
It’s usually not a good idea to act as useful idiot for the Left in their endless quest to denigrate and legitimatize America, unless your goal is to help them do it.
