The worst thing gaming has ever done was think it was anything like professional sports. I think that I'm in favor of cheating in games just because it rankles people who take gaming way too seriously.
Every activity has its own popularity, and number of fans of various seriousness... Cat and dog shows, caber toss, curling, singing competitions, on and on and on, the list is about infinite, since it encompasses everything within which someone could potentially be more skilled.
Singling out video games among all the other things humans do competitively feels like a personal bias.
I personally don't care about probably 99% of the 'competitions' out there, but I don't give anyone crap for being obsessed about their own thing.
(I don't play games online multiplayer style, so I'm not in the target group anyway.)
I don't think there's such a thing as "gaming", as you use the word... everyone involved does their own thing, in infinite variety as well.
Sure the technological barrier is important, but I fail to see how they're categorically different depending on what they require of the participants.
I don't have an issue saying they both should not be taken seriously, or that both should be taken seriously, but to draw a line between them in terms of "seriousness" I think needs elaborating to me.
Also stupid. Athlete worship is as bad or worse than celebrity worship. The obsession with and tribalism from professional sports has creates some of the most obnoxious bores in the world. All for a bunch of people kicking or throwing a ball around.
