He is a liar. Where did he even get that story if he didnt make it up?The OP is a lie. The Union Army didnt hang John Brown. The state of Virginia did.
Virginia v. John Brown - Wikipedia
He isnt a liar. Like you before you googled it he didnt know.
A standard ploy by lefties.
Identify any error, no matter how meaningless and claim it is a lie.
Then the debate is sidetracked into a stupid debate, where the vile asshole lefty gets to spend their time attacking the character of the person they hate, while avoiding the issue.
Because they are nearly ALWAYS on the wrong side of the issue.
And they know it.
