Before we commence to an argument, lol, I will 100% agree with you that people need to change their behavior as it relates to food addictions, mentally, more so than relying on a surgery alone to lose weight.  This is why so many people fail after WLS.  
I see what you're saying and will agree that WLS will HELP jumpstart a transformation, but no, it is not 100% guaranteed.  It's a proven fact.  Go to thinnertimes or other WLS websites and see the countless people who have failed.  If you use it properly, as a tool, then yes it is very successful, but if you don't put in 100% and change EVERYTHING, it will not work.  Again, you can't just rely on a surgery without effort.  (I know of a lady just two weeks ago who had WLS and had a family member sneak her in a burger king whopper while she was 1 day post op, in the hospital...)
In addition, I am now bulking (4,000cals per day)and can eat anything I want.  If I did not lift and keep my diet in check (even when clean bulking), I would gain it all back by way of fat.
I'm not cynical, nor am I at all offended at your or anyone else's comments if they're negative towards my transformation personally.  In fact, you can't even tell I had surgery anymore, and if I wanted to, I could bury it down and never bring it up again...I'm making a point now to educate those that were like me, and to stick up for them when people don't give them the credit they deserve.  It's unfair to categorize a person's success into a surgery, just the same as it is to look down on any IFBB and categorize their wins based on usage.
