If, by dividing America you are referring to Trump holding the criminals accountable and the criminals feeling betrayed is division - you are probably right.    If you think that by Trump protecting trafficked persons and prosecuting their sick and twisted abusers is dividing, then you are probably right. Perhaps you are meaning that by Trump holding the top government officials in the country responsible for treasonous acts against the American constitution and people  and those people feeling vulnerable and unprotected (as they were invulnerable and heavily protected in the previous Administrations) is a justifiable definition for saying Trump has divided America, then you are again likely right. If the above are, in your view, correct, then you are right, Trump has divided America. I hope I didn't miss anything, I am making soup, shovelling snow and composing this reply in simulcast.
