It was a nazi rally organized by nazis where they literally marched down the street in columns at night with flaming torches shouting "blood and soil" and "the jews will not replace us," both Nazi slogans. One of the nazis rammed his car into a crowd a anti racist protests at high speed, killling 1 and injuring dozens.
This is the rally he replied to with "there are fine people on both sides." He then hedged and said he didn't support nazis, seconds after supporting nazis.
It's almost like the man could have flat out condemned nazis with no intentional ambiguity, but nah.
