1. Conor McGregor
When McGregor rose to superstardom, he took the Irish nation with him. After several one-sided losses, however, now almost everyone dislikes him because of his embarrassing antics. The Notorious suffered numerous arrests for multiple assaults and driving violations. Meanwhile, his online behavior turned many people against him because he takes rivalries too far. In 2021, he insulted Khabib Nurmagamedov’s deceased father before deleting the tweet.
McGregor also infamously punched an older man in a bar in 2019. Then, he bought the bar and banned his victim from returning. Meanwhile, he faced numerous allegations of sexual assault over the years with reported settlements. These days many fans watch his fights because they want to see him lose. He makes it very easy to hate him because he keeps digging a hole for himself.
