For many who hate Johnson, the reason is he is a serial liar. As a journalist, he was twice fired for faking quotes and he falsely claimed that drunken Liverpool fans were responsible for the Hillsborough disaster. As a junior minister he was fired for lying to his boss Michael Howard about his long-term extramarital affair. As a leader of the Vote Leave campaign he blatantly and unashamedly lied about Brexit freeing-up £350m pw for the NHS and Turkish nationals being about to flood in to swing the vote. Currently the Supreme Court is deciding whether he lied to the Queen to secure her approval for closing parliament to deny MPs the opportunity to scrutinise and debate his Brexit plans.
For the non-deferential, the Eton and Oxbridge-educated and privileged Johnson is, like most of his ilk, out of touch with ordinary people. Even if he is clever enough to latch onto popular issues that concern ordinary people, or the tabloids for the cerebrally challenged have encouraged them to be concerned about.
