Biden speaks like a traditional politician so he's not going to use overt violent language. I would argue, however, that Biden, as President of the US, has used divisive language.
During his speech delivered in Philadelphia on 9/1/22 (the dark red speech) titled "The Continued Battle for the Soul of the Nation." the President strongly condemned "MAGA Republicans" stating "they represent an extremism that threatens the very foundations of our Republic." He also said that "MAGA forces are determined to take this country backwards." "The Republican Party is currently dominated, driven, intimidated by Donald Trump and the MAGA Republicans," calling this a "threat to this country."
