I agree, too. I think much of Bieber's present-day jerkassery may be due to this in fact. At least that could be one of the reasons. The Selina Gomez breakup can only explain so much.
I prefer that he was the cute, mop-haired girlish prettyboy than the thug wannabee he's trying to be now. Even though all his musical output is pure plastic bubblegum, I never had any real hate for the guy. I hate what he became, though. I'd rather Bieber be a cute, mop-top, smiling, down-to-earth, playful prettyboy that folks made fun of than the young slug in stupid "ghetto" clothes with the Vanilla Ice hair, dorky owl tattoo & peeing/spitting on everything habit (that makes everyone barf). He wants so hard to be "a maaaaan" that he's acting like a rabid baboon.
This is what the "Macho Masculine Kyriarchal Ideal" does to ya, kids....especially if you happen to be slow-developing, baby-faced 18-19 year old men who have barely left puberty.
The pressures of fame could be a factor, too....or perhaps he was always a brat, who knows?
Frankly, it's apparently considered "cool" to have a rabid hatedom for certain groups, musicians, shows, etc. and the people who like them. Look, some folks dig Green Day, Skrillex, Boston, Britney Spears, Bjork, Motorhead, Gilligan's Island, The Brady Bunch, Twilight, Justin Bieber, or whatever...they should GET OVER IT! Just because they loathe it doesn't mean they have to loudly broadcast it to the point of being a bullying idiot. The hater looks even more ridiculous than the stuff/fans they decry.
Same goes for haters of Furries & LARPers. Who cares? Some folks dig anthropomorphic critter-people, some like live-action role-playing. They're not hurting anyone. Let them be. People who hate those guys are like the Jocks & Cheerleaders ('OOOOhhhh! NEEEEERDS!'). Screw them! Noone's putting a gun to their head and forcing them to don a wizard gettup or goofy animal suit! Let's the dorks be dorks! Dorkiness can be neat! Weirdness results in creativity! I'd rather see a guy with a hard-on for the voluptuous delights of Minerva Mink than, say, an actual mink...or a 4 year old!
