Your example of why horse riding is physically demanding was "it fucks up your back", but dismissed examples that show that esports also can cause injuries. Know what also fucks up your back? Factory work...
Nobody tries to mock sports like horse riding but rather show that esports is quit equally demanding on a comparable level.
Oh dear lord. It was not an invitation to tally every minor niggle down to the last hemorrhoid. It was a quick quip.
Esports is nowhere near horse riding, it hovers around darts. That's the point. You are so far removed from knowing anything about those sports and more involved physical activity, that you can throw out falsities and casually shit on them in favour of esports. And you are unable to comprehend this.
You value esports, and are invested in putting it in the best light possible. So every little thing turns into the most serious version of itself. Esports is super impressive, the reflexes, the speed. It's dangerous too! You get carpal tunnel. It takes hard work and dedication to hone this craft! Spitshine to put on a pedestal. And then you turn towards sports you don't give a crap about. Suddenly, there's nothing to talk about. Clearly, that means there's so little to this! Shooting a gun, riding a horse, that's all it is. Your opinion is solely informed by you buying into your own embellishment of esports and your lack knowledge or care for any other sport.
