It's not hate, more like just dislike. No doubt Jorge has been in the top 3 riders for at least 6 years now. He may be the "best" rider in the world. But I think some people "don't like" him for a few reasons.
1) His "style," while deeply impressive, can be rather boring in actuality. No one else on the planet can even come close to riding a bike that fast, and that smooth. Most people couldn't even be that smooth if you let them go as *slow* as they wanted. Lorenzo is mindbogglingly smooth, the quintessential "inch-perfect" rider, hitting the exact same piece of tarmac lap after lap. Even down to his movements on the bike, like his foot on the peg, how it's positioned at that sort of awkward angle right up until he's increasing lean angle and gets about 10-15 degrees from full lean, where he moves it a few inches to get the toe out of the way. Every fucking corner, that exact same movement. It's is unreal, but you have to admit, it can become somewhat boring to watch when he's just cleared off at the front and grinds out the laps all the way to the end. No?
2) He doesn't seem up for a full on bar banging battle. He preferred the Lorenzo-Stoner-Pedrosa "gentleman's agreement" instead. When we've got guys like Rossi-Marquez-Iannone to entertain us, well, who would prefer to watch Lorenzo's style of duel?
3) He seems to be really insecure, or whatever other word you want to use for mental problems. Crying on King Kenny's shoulder. His wet weather vaginal flareups of late. Hell, just the other day when Aleix won the pole, Lorenzo made that comment about how he was "first on normal tires," he couldn't even let the Suzuki guys enjoy the moment. I remember in 2013, at the end in Valencia, Jorge won the race but MM was world champion. And yet Jorge's victory celebrations were over the top. It was like, "Really? Are you really so thrilled about winning this inconsequential race, when you lost the championship, and the season is now over and everyone is ready to pop the cork on Marquez' unheralded rookie season championship?" Every race win he has to do his stupid black mamba thing, or same stupid jump from the top step and fist pump. I don't know man....he just kind of seems like an insecure putz.
