One of the questions Trump should drill Biden with at the debates is Biden's stance on BLM/Antifa thugs vandalism and violence. It would be very interesting to see Biden try to sidestep the question.
If he says he condemns the violence, he will irritate millions of pro BLM and Antifa idiots.
If says he supports the violence in the name of social justice, he'll upset many voters who still believe in law and order.
