To put it more bluntly, part of Trump's appeal to many is that he's not afraid to flip the bird to people who deserve it, regardless of it being uncouth, and beneath the usual dignity of the office.
I didn't support him in the primaries, and was wavering on whether I'd even vote for him in the general election. But when I saw how the left was acting in 2016, and what they've done since...I'd rather than a guy who fights dirty than a gentleman who'd say "thank you sir may I have another."
I hate them.
