No, Trump is actually more unifying in his rhetoric than any recent national politician I know of except for George W. Bush. Again, leftist propagandists routinely lie about his comments as they do with other innocent people they smear, and you're stupid enough to be easily manipulated by that crap.
I've never heard Trump attack regular Americans of any race, creed, sex, or even political affiliation. He attacks celebrity and political individuals, usually after they attack him first, but he appeals to rank and file liberals to vote for him. By contrast Democrats regularly attack regular Americans as "deplorables", "racist", etc. That stuff really does cultivate hatred between Americans, not Trump's speeches.
