Okay let's work through this.

Their propositions:

SJW P: All men are born rapists.

SJW Q: All men are guilty by default.

SJW if P then Q: If all men are born rapists then all men are guilty by default.

Quite the claim.

Our propositions:

Human not P: Not all men are born rapists.

Human not Q: Not all men are guilty by default.

Human if not P then not Q: If not all men are born rapists then not all men are guilty by default.

Therefore, the only hope we have is in proving that not all men are guilty by default. And in doing so we prove that not all men are born rapists. This would be a huge victory for mankind.

So what it boils down to is we either let them win and due process gets destroyed or we don't let them win but we will have to start over at the beginning.

Not impossible, but I suspect the latter would be bloody.
