So why exactly do people get flustered over wrestling being "fake," when they so quickly get emotionally attached to TV, movies, and other fictional media? Perhaps it's because wrestling world championships are treated with colossal importance, and are life-affirming events for the wrestlers that win them. But if everything's scripted and planned, then why do wrestlers cry tears of joy when they win a world title? Doesn't it actually mean as much as a third grader declaring himself the crown prince of Uranus?
Here's the issue: thinking about a pro wrestling title being earned like any other combat sport title is the wrong way to do it. It's less "winning by knockout in the third round," and more "getting a bonus or promotion at work for doing an excellent job." If somebody wins a world championship in wrestling, it's a reflection of years of hard work on the wrestler's part. That grappler had to build up their character (or destroy and create new ones), endure years of putting over other wrestlers and embarrassing storylines, and earn the love (or ire) of the fans.
Plus, being a world champion reflects the confidence the company has in that wrestler to represent the company, although some wrestlers like Mick Foley, Daniel Bryan, and Steve Austin didn't get that confidence at first. It was only after they turned the fans to their side, and made themselves impossible to ignore, that the company was forced to put the title on them. Obviously, it's a matter of debate on which wrestlers have earned their push, but there usually is no doubt work has been done.
So if you're still mad about wrestlers getting emotional when they win a world title, then it's time to get mad at Leonardo DiCaprio for caring so much about finally winning an Oscar. After all, he didn't really fight that bear. It was fake.
