Heading into one of the biggest fights of his life against Andrei Arlovski in the co-main event of this Saturday night’s (September 5, 2015) UFC 191 from the MGM Grand in Las Vegas, two-time heavyweight champ Frank Mir wants all those spewing mindless hate on the Internet to know how he feels about them.

Beginning at the 14:53 mark of the above recent interview with FightHubTV (via Bloody Elbow), Mir gave a brutally honest perspective on the fight fans online that do nothing else but make fun of others behind the protective wall of a computer screen:

“Your life sucks. All you people out there that wanna sit on the computer and be unhappy that your life sucks, so you think everybody else when they go out there and you see them on the side of the road and, you know your personality types – you sit there and you see that guy jogging, who’s 40 lbs. overweight and you make a joke, like ‘yea buddy, nice try’…It’s like no, that dude’s out there trying.

“Whether he fails and the next day he doesn’t show up because he’s sore, but you know what, in a week he’ll try again. Stop being that guy that throws insults or be that guy and be miserable and I feel bad for you because you really have the worst life of all.”

The always outspoken Mir has called out online haters in a big way after rebounding from a brutal four-fight losing streak that had several people that he’s referring to calling for his immediate retirement.

The 36-year-old heavyweight pioneer had the wherewithal to persevere and re-tool his game to shining results. With two knockout wins over Antonio Silva and Todd Duffee in 2015, Mir could find himself on the cusp of an unlikely title shot if he can defeat the No. 4-ranked Arlovski this weekend.

If he does, it’s going to be tough to call him out after he’s solidified himself as an elite UFC heavyweight dating back to the early days under Zuffa.
