Identity? Nah, I couldn't care less. I'm just myself and I happen to not like Punk very much (or rather, at all). I also have no goal to be some kind of forum #1 heel for Punk fans or anything of that sort. I'm just very vocal in regards to what I think and I guess that makes me stand-out and annoying to some.
I'll be the first to admit that I was supportive of him when I first joined this forum for the first few months. But then as his reign and face run went on, I just grew tired of him and felt that he was nothing more than a one hit wonder who had one great month back in July 2011. I remember even trying to force myself to enjoy seeing him pretend to vomit in the middle of the ring as well as being a hypocrite who idolizes Stone Cold but bashes Chris Brown for beating Rihanna. That said, I only really liked him during that one period and hated him from the first time I laid eyes on him. But now that I think about it, ANYONE would've gotten over with me given that shoot promo - so that was just a one-time fad lasting for a bit longer before I realized that there's nothing special about this guy.
And I would NEVER defend Cena's character. I've just accepted it because he'll never change. And with Cena, he's naturally a favorite of mine so that makes it much easier for me to "accept him for what he is" compared to Punk who has changed the main part of his character several times in the past few years and I only liked one of them ("the kayfabe breaker" that would be).
And next in line? LOL. First of all, I NEVER hated him because he is not a draw. That's just fucking stupid and I don't know why anyone would get that impression from me. Sure, I've argued against him in the ratings topic many times but never was it a reason for me to hate him. Just a fun bonus that would be good material to get under his marks' skin and a justification for why he shouldn't be pushed. The other things you mentioned, they are all part of why I don't like him (except vanilla midget*). He's annoying, he has a terrible look making it not so fun to watch him in the ring and just being boring in general by whining about the same shit every week which his fans eat up every time. And you mentioned not liking his face and I have to say that's another thing. He just has a punchable fans that I can't stand looking at which does him no favors in being liked by me. It's never been displayed any better than in this pic below:
* = I'm a fan of Rey Mysterio, Chris Jericho, Eddie Guerrero and my favorite wrestle is Chris Benoit. None of them are exactly tall, so I'd be a hypocrite to like them but bash Punk for his size.
This pretty much sums up exactly how I feel too, except I'm not really a Cena fan (not a hater at all either though, since I understand why he doesn't change character).
For me, I liked CM Punk at the same time as everyone else; when he got put against Cena then put over back at MITB 2011. Actually I liked him a bit before that as the New Nexus leader. He had a couple cool/funny moments. Thing is, I expected more from him after he got billed as "the guy", and he didn't deliver.
It wasn't a big deal at first until I began to notice they were trying to book him as a fake Austin (going against HHH), then a "cooler Cena" by getting put in so many "he overcame the odds" type matches (glorified handicap match against Miz and Del Rio, glorified handicap match against Ziggler with Laurinitis as the special guest ref, then glorified handicap/gauntlet match at Elimination Chamber) getting put over every time.
That's when I had enough. It was clear he wasn't that cool rogue element that he first appeared to be, and was just another one of "Vince's choices" as people call them, guised as being something different to generate temporary interest when he just wasn't. It was the same thing in a different wrapper. Upon closer inspection, I didn't like the new wrapper.
In this way though, Vince has done a good job at making fans think Punk was the new era, the new thing, or the harbinger of change. In the end, nothing's changed except Punk's been given tons of spotlight and Cena hasn't had the title since Punk's had it. Not really a big difference to me. It just pulled out Cena and replaced him with Punk, while booking Punk in the same, always winning fashion as Cena.
I remember a time when you didn't speak so ill of Punk, but when he got the title and the reign started going on past a few months, you just grew more and more to loathe him. Kinda typical, how the IWC turns on one of their darlings.
Have you ever stopped to think people turned on him because he got boring? Or that they expected something much better after he was handed the keys to the show?
Not everything is because IWC turns on everyone. Some people's opinions evolve over time as a person's character and flaws become more apparent.
