Possibly. I sure don't.
ANY accusation the left makes about the right is going to be at the very least superficially plausible. Those accusations only gain so much power as the right grants their plausibility.
Generally I would agree. With respect to the Gadsden flag do you know anyone on the right who believes it to be offensive? I do not. But we can see that there are some folks - even on this site - who do hold that opinion about the battle flag. Even among conservatives there is disagreement.
Granting those accusations ANY plausibility is nothing less than betrayal of ones idealogical coworkers.
Nonsense.
Do you know anyone on the right that advocates slavery?
If no one on the right advocates slavery, by what rationale does one from the right countenance accusations that imply the right does advocate slavery?
